IIS Express 503 after working fine for days with blazor app #17781

Closed vsfeedback closed 3 years ago

vsfeedback commented 4 years ago

This issue has been moved from a ticket on Developer Community.


Very frustrating to be starting on a new project and IIS Express suddenly starts serving up 503 errors for no apparent reason.

Seriously, I'd run several times this morning and then with a simple code change of adding a new image to my index.razor, it's suddenly 503s. I undid my change, even restored my backup from yesterday. Tried just serving up a static image.

I've attached the log file showing the port hasn't changed from when it was working. There were no project changes, updates, etc that went on. It just plain stopped. There's zero entries in event viewer beyond the standard security auditing successes.

If I switch to using kestrel, it works fine. If I switch to my traditional asp.net site, IIS Express works fine.

launchSettings.json iisSettings url/sslPort match what Show All Applications have in IIS Express and match the applicationHost.config bindings. I tried netsh http add urlacl url= for both the http and https versions of the url. I turned off Enable SSL in the project properties. I turned off my firewall. I did a project clean. I deleted the .vs folder so it could all rebuild. Still nothing but 503s.

I can certainly continue my development using kestrel but it's a huge red flag when something that has worked for a week stops functioning without any logical reason why. Searching about IIS Express errors is a minefield of it breaking constnatly and all sorts of steps to take to try and get it to work for older .net apps.

Thanks for contacting us. @shirhatti can you please look into this? Thanks!

Unfortunately there isn't enough information in the issue for this to be actionable.

I have questions for the OP, if we can contact them:

  1. Can you share the applicationHost.config folder generated by Visual Studio in the .vs directory when you're application starts 503ing?
  2. Do you see anything in your Windows Event Logs corresponding to the 503s?

Sorry, I had posted the VS feedback on Nov 19th and have just carried along without IIS(which has created all sorts of frustrations of publishing to discover things don't work). I just switched to IIS to get the 503 again.

EventViewer Application indicates 2264 "The directory specified for caching compressed content C:\inetpub\temp\IIS Temporary Compressed Files\WinVoiceLanding AppPool is invalid. Static compression is being disabled.". Folder is present. If I delete the folder and try again, it's recreated properly. EventViewer System indicates 10016 "The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID {2593F8B9-4EAF-457C-B68A-50F6B8EA6B54} and APPID {15C20B67-12E7-4BB6-92BB-7AFF07997402} to the user JASON10\nxtwo SID (S-1-5-21-2849887746-3368035124-555417860-1001) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.". 2593F8B9-4EAF-457C-B68A-50F6B8EA6B54 is PerAppRuntimeBroker

Here's my applicationhost.config. It's WinVoiceLanding.

        The <configSections> section controls the registration of sections.
        Section is the basic unit of deployment, locking, searching and
        containment for configuration settings.

        Every section belongs to one section group.
        A section group is a container of logically-related sections.

        Sections cannot be nested.
        Section groups may be nested.

        <section
            name=""  [Required, Collection Key] [XML name of the section]
            allowDefinition="Everywhere" [MachineOnly|MachineToApplication|AppHostOnly|Everywhere] [Level where it can be set]

            allowLocation="true"  [true|false] [Allowed in location tags]
        />

        The recommended way to unlock sections is by using a location tag:
        <location path="Default Web Site" overrideMode="Allow">
            <system.webServer>
                <asp />

As a note as to some of the frustrations about not being able to use IIS on my development machine, here's an example from earlier in the week that too me too long to track down:

This works kestrel but 503's on production IIS

using (StreamReader iisUrlRewriteStreamReader = File.OpenText("IISUrlRewrite.xml"))
            {
                var options = new RewriteOptions()
                    .AddIISUrlRewrite(iisUrlRewriteStreamReader);

                app.UseRewriter(options);
            }

resulting in me needing to switch to adding directly like this(that works on both)

var options = new RewriteOptions()

            .AddRedirect(@"^contact\.htm$", "/Contact");

Took me forever to track down what was going on. I assumed AddIISUrlRewrite was simply using IIS URL rewrite file format to the rewrite middleware, not actually communicating with IIS.

resulting in me needing to switch to adding directly like this(that works on both)

So to be clear here, if you switch the rewrite rules to be directly added instead of read from the file, your issue is resolved? Is that correct?

Could it be possible that the user under which the IIS app pool can't access the file? Do you get any exceptions trying to open the IISUrlRewrite.xml file?

Incorrect. I was giving an example why not being able to run my site using IIS Express on my development machine has created serious deployment issues for me.

analogrelay commented 4 years ago

Gotcha, thanks for clarifying. So even if you specify the rules manually it doesn't work?

NXTwoThou commented 4 years ago

Manually doing the rules worked fine which is why I moved on. I was using that to point out as an example of why not being able to use IIS Express on my development machine for .NET Core testing created a serious problem between development and deployment.

Not necessarily disagreeing, I'm trying to identify the repro so we can get to actionable work. I would expect loading from a file to be different in IIS and IIS Express, since in IIS Express the app runs as your local user, but in IIS the app runs under a Windows Service account.

So then to be clear, the issue only occurs if you read the rules from a file, and not if you configure them manually?

This works on both development and production:

var options = new RewriteOptions()
                .AddRedirect(@"^(products\.htm|product\.htm|pro\.htm|junior\.htm|net\.htm|price\.htm|plus\.htm|manual\.htm)$", "/WinVoice")
            .AddRedirect(@"^(indexold\.htm|index\.htm|compare\.htm|faq\.htm|new\.htm|free\.htm|pecos\.htm|download\.htm|index2\.htm|wwds\.htm|links\.htm|winpcs\.htm|bar\.htm|addrem\.htm)$", "/")
            .AddRedirect(@"^(cgi-bin|discus|wvpro26).*$", "/")
            .AddRedirect(@"^contact\.htm$", "/Contact");

            app.UseRewriter(options);

This works on development but not production:

using (StreamReader iisUrlRewriteStreamReader = File.OpenText("IISUrlRewrite.xml"))
            {
                var options = new RewriteOptions()
                    .AddIISUrlRewrite(iisUrlRewriteStreamReader);

                app.UseRewriter(options);
            }

I'm afraid I got had long since got rid of the xml file we were using. Note, while frantically trying to figure out what was going on with production, I actually changed the user to be an admin on the box to see if it was a permission issue.

You changed the user of the worker process?

NXTwoThou commented 4 years ago

Well, the AppPool identity

analogrelay commented 4 years ago

File access is the main thing that gets messy when moving from IIS Express to IIS. I'm not sure there's much ASP.NET Core can do about this since IIS controls the identity of the process entirely.

If the rewrite xml file was deployed alongside the app, I wouldn't expect a permissions problem. Even more so if the worker process was an admin.

One more diagnostic thought comes to mind. Would you be able to try loading the file completely in to a MemoryStream first (behind a try catch that logs any errors) and then call AddIISUrlRewrite with that? I'd expect an error when reading from the file that should have more detail. Example pseudocode below.

If you'd rather just stick with the change you made to remove the file rather than investigating deeper that's fine, I understand the priority for you is getting your app working 😄. There are edges between using IIS Express and IIS, it's unfortunate but it's where we are right now. Kestrel is now fully supported as a production front-end server, so if you don't need IIS features, you can certainly use that to get a fully consistent server experience in both development and production.

Pseudo-code for loading into memory first (it's probably right, but may need a few minor tweaks that I missed since I'm not in front of a compiler at the moment ;)):

// Memory streams don't need to be disposed, so no need for a using block
var stream = new MemoryStream();
try
{
    using (var fileStream = File.OpenRead("IISUrlRewrite.xml"))
    {
        fileStream.CopyTo(stream);
    }
}
catch(Exception ex)
{
    // Log or otherwise capture this error

    // Rethrow, since the rest isn't going to work now
    throw;
}

// Flush and rewind the stream
stream.Flush();
stream.Seek(0, SeekOrigin.Begin);

var options = new RewriteOptions()
    .AddIISUrlRewrite(iisUrlRewriteStreamReader);

app.UseRewriter(options);
NXTwoThou commented 4 years ago

I think there's some confusion. I'm -unable- to use IIS Express on this project on my development machine for this asp.net core blazor project. It was working fine one day, then stopped for no apparent reason(IIS Express works for our non-.core projects).

The URLRewrite rabbit hole was me giving a very specific example where not being able to test with IIS Express on my development machine created problems when I tried to deploy to IIS on production.

AKA, if I want to test your recommended code change, I'd have to push it onto production. I got a deep enough talking to after the mentioned fiasco that I'm a little gun shy to play with it(at least until my work load slacks off some)

analogrelay commented 4 years ago

@NXTwoThou I see, I think you're right about the confusion. Let's focus back on the original issue though. If you're still able to repro this by switching back to IIS Express, can you look at our Troubleshoot on IIS guide? There are instructions there on how to collect information from the Event Viewer (you indicated there wasn't anything useful there though), as well as detailed logs from your application's stdout and a debug log from ANCM itself. All those logs would help us better identify what went wrong to cause the 503 errors.

NXTwoThou commented 4 years ago

Unfortunately the instructions sent are for identifying issues with IIS. IIS on production is fine. Debugging/running from Visual Studio with IIS Express is not fine(just tried with Visual Studio 16.4.2, even started as Administrator to try and eliminate security issues).

The first, primary issue is this: When I hit the green arrow in visual studio to debug an app, Where is the "Directory structure" detailed in the help? On production, it's easy, it's where I publish it. I have 7 locations where myappname.dll is found on either of my drives. myappname\bin\debug\netcoreapp3.1 (and release). myappname\obj\debug\netcoreapp3.1 and \netcoreapp3.1\RazorDeclaration. myappname\obj\release\netcoreapp3.1\pubtmp\out and myappname\obj\release\netcoreapp3.1\RazorDeclaration.

If I run a Clean from visual studio on my project(switch back and forth between release and debug), I'm down to 1 of them. myappname\bin\release\netcoreapp3.1\pubtmp\out They have the same file date as the last time published to production.

So, with that in mind that I have no idea where I'm supposed to be looking based on the provided instructions, here's what I did: Application Event Log. Cleared log Ran with IIS Express. Edge loads and displays "This page isn't working right now localhost can't currently handle this request. HTTP ERROR 503" Refreshed event log. Zero application log entries.

If the "deployment" folder is the bin\debug\netcoreapp3.1\ folder.. Ran donet .\winvoicelanding.dll no errors Ctrl-c to get out of it The folder did not contain a web.config. I copied one over from production. Set stdoutLogEnabled to be true, created logs folder. Added handlerSettings with a valid log file path. Tried debugging from visual studio, no logs created. Added the environmentVariables section to the web.config, tried debugging from visual studio, no logs created.

Tried copying the web.config into the root of myappname, same results Took a look at the .vs\solutionname\config\applicationhost.config file. The virtualDirectory set for myappname is the myappname folder. I tried changing it to myappname\bin\debug\netcoreapp3.1 folder and was able to get it to actually display something(with errors as contents of wwwroot not rending properly).

NXTwoThou commented 4 years ago

As an update, installed Visual Studio v16.4.3 today along with .NET Core 3.1.1. Same results. I went through and cleaned up a bunch of old .NET Core sdk's/hosting packages/runtimes hoping it was something stuck there, but no dice. dotnet --info showed 2.1, 2.2.6, 2.2.7, 2.2.8, 3.0 Preview7, 3.0, along with 3.1.

Unfortunately the instructions sent are for identifying issues with IIS. IIS on production is fine. Debugging/running from Visual Studio with IIS Express is not fine(just tried with Visual Studio 16.4.2, even started as Administrator to try and eliminate security issues).

Those instructions should also work for IIS Express. You should be able to enable the debug log by using "File > New Item..." in VS and selecting "web.config" to place a web.config file in the root of your project (next to the csproj). VS should use that when you run with (Ctrl-)F5 (or the green play button). Is that what you tried when you mentioned putting a web.config "in the root of myappname"? If so, can you attach the web.config you ended up using?

You can configure the stdout and debug logs using a web.config like this:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <handlers>
      <remove name="aspNetCore" />
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
    </handlers>
    <aspNetCore processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" hostingModel="InProcess">
      <handlerSettings>
        <handlerSetting name="debugLevel" value="file" />
        <handlerSetting name="debugFile" value=".\logs\ancm.log" />
      </handlerSettings>
    </aspNetCore>
  </system.webServer>
</configuration>

That should produce both a .\logs\stdout_... file (one per launch) and a .\logs\ancm.log file in your project directory. If you can attach those files (you should be able to drag-and-drop them in to the comment box, you may have to change the file extension to .txt; they can be large so copying the content makes the layout messy) that would help us diagnose this issue.

NXTwoThou commented 4 years ago

I had put it in the bin\debug\netcoreapp3.1\ as that's where the dlls were. There was no web.config in the folder that had my csproj. When I put your example there, I actually got a log file! The logs quickly told me what was going on.

Visual Studio's publish feature has issues with trying to publish a .NET Core site. Namely, if you are trying to publish to production, you can't because files are locked. There's no option for publish to send over an app_offline.htm file first. Due to this limitation, I created an app_offline.htm file in where my csproj file is and a batch file to copy it to the three production servers that I run before I start publishing. With a web.config file in that same folder, it then created the logs that clearly stated "[aspnetcorev2.dll] Detected app_offline file, creating polling application". Once the file was moved out of the way, of course everything loaded up.

AKA, the issue was 100,000% of my own creation.

Thank you so much for your assistance, sorry for the struggle.

There's no option for publish to send over an app_offline.htm file first.

When publishing to Azure App Service, we do send an app_offline first. I'd have thought the publish via "Web Deploy" would as well. How are you publishing to IIS? Are you using VS's built-in publishing? If so, what kind of publish profile have you configured?

Glad your issue is resolved! I'm not going to close this yet because I'd like to see if we can figure out if you need the manual app_offline management at all, but I am going to move this to Discussions.

NXTwoThou commented 4 years ago

To be fair, I haven't tried more recent versions of Visual Studio to see if it copies a app_offline.htm first. According to my batch file create date, I did that December 3rd when I tried my first update to the site and ran into files being locked issue.

analogrelay commented 4 years ago

Ah, I see. You're publishing to a folder. Yes, that won't do app_offline.htm. You have to use a publishing system like Web Deploy to have it automatically do the app_offline.htm dance.

NXTwoThou commented 4 years ago

My other web apps use "Publish method:" "File system" and I've never had any issue in the last 18 years with locked files...

analogrelay commented 4 years ago

For ASP.NET Core apps? That would be surprising. It should always have required restarting the server.

ASP.NET (System.Web-based) apps did support this kind of publishing because the runtime did a "shadow-copy" (duplicated the entire application at startup), but that caused a lot of other problems since the app wasn't running from the directory you thought it was.

NXTwoThou commented 4 years ago

For classic asp.net "Web Site" projects(one was started in 2002..stares lovingly at the green Visual C# .NET Standard 1.0 box on his bookshelf). The only reason I know about app_offline.htm at all is if you have any sort of error/crash while "file system" publishing, the orphan app_offline.htm file is in the folder(I did a quick search to make sure I wasn't crazy remembering it). It's happened to me probably 4 times over the years.

So, basically, classic asp.net "file system" publish will first copy app_offline.htm over, asp.net core "file system" publish will not. It would be nice if the publish settings of asp.net core apps it gave the option to do the same behavior.
