OpenQA.Selenium.WebDriverException : No response from server for url #3719

Closed lukeis closed 8 years ago

lukeis commented 8 years ago

Originally reported on Google Code with ID 3719

When using ChromeDriver via ChromeDriverService and RemoteDriver
and run multiple tests. They _sometimes_ fail with the exception above.

The tests run OK when I start individual ChromeDriver per each unit test.

The stack is as follows:

I'm still seeing this with latest chromedriver, grid, and selenium.  

Running tests on the local computer through chromedriver works great, but I run tests
through a grid(on the local machine) the failure rate goes way up - lots of these No
Response exceptions.

I see this error with windows 2003 R2, firefox 13, using webdriver.
it just started occuring recently, for me.

Also with the most recent chromedriver this happens frequently as well
on windows XP sp3 with chrome 20, 21, or 22. i resorted to disabling the updates for
chrome to keep the chrome 20 driver able to work.

I've read elsewhere that it may be a request limit (for proxy servers having too low
of a conection limit), that causes the server to return null and crash with the "No
response from server for url" exception. 

The "No response from server for url" exception seems to occur whenever a request by
the server returns null or an empty response at which point the server crashes.

It Might be a load related issue, as in when the load of requests is too much for the
drivers to carry, then they throw the  "No response from server for url" exception

All my tests broke today with the following error

OpenQA.Selenium.WebDriverException : No response from server for url http://localhost:7057/hub/session/283a5d58-82dd-483b-a3ef-0ff3ee37841c/element

Am on WebDriver C# bindings 2.25.1 Win 7,FF 14/13

They all worked fine until early today nothing has been changed.
However if i rerun them again they work alright a few times.

Are we going to get a fix for this in future releases ?

Hi, I'm solved it
if there are no timeout (based on machine speed - usually thread.sleep(250) works fine)
between interactions with driver - driver couldn't throw event from browser to test
- and you gets error.

And watch at some "Explicit Implicit Wait Webdriver" articles.

We are seeing the same issue intermittently on Chrome and Firefox. Unfortunately, it
is not feasible for us to add sleeps between each interaction with the WebDriver given
how widely it is used.

Is there any traction on when this issue will be solved?

What, exactly, would you like the .NET bindings to do? That's not a question asked to
be flippant, it's a genuine question. Before you answer, though, please see http://jimevansmusic.blogspot.com/2012/11/net-bindings-whaddaymean-no-response.html
for a more in-depth explanation of exactly what's happening when you receive this error.

What would be quite helpful in many cases is to add the raised WebException as an InnerException
in the WebDriverException you throw. This will allow clients to investigate the underlying
causes and the perform their own retry logic if appropriate.

It could very well be to do with the Implicit Wait option. If you are using it, and
are getting this message, what happens when you remove it?

I don't know if this will help, but I just starting seeing this issue this week. My
intern started seeing it last week. At first I thought it was just his machine, as
I was not seeing it. Yesterday it started showing on my machine.

I built a testing app around the WebDriver that tests a web based Learning Management
System for our regression testing. As far as having a reproducible scenario, I might
have one. I am seeing this in only one portion of my test (e.g. clicking a link to
access the work submission page of an Activity created by the testing app) and it happens
pretty regularly. It's on a Click() and the click happens, but WebDriver is stuck in
the code on the Click event, as if it's waiting for a something. The testing app won't
get past the third (of five) activities for the first (of four) students without throwing
an exception. This is the only place that I see it and it is in probably the most in
depth tests that I have made for the app. The tests in all my other suites pretty much
pass as I would expect them to. 

I just upgraded from VS2010 to VS2012 hoping that might help. It didn't.

Using Visual C# 2012 Premium, WebDriver 2.21, Firefox 18, Chrome 23.0.1271.97

I would be willing to help in any way that I can

To those who've run into this issue, please update to 2.30.0 of the .NET bindings when
they are available. I've made a change to the .NET bindings[1] that should allow us
to have more diagnostic information in the exception that is thrown when this happens.
Please note that this change I've added *WILL* *NOT* *FIX* the problem. It is only
intended to provide more details so that we might be able to narrow down root causes
to the issue a little more cleanly.

I quit seeing this error all together when I explicitly set the command timeout via
the driver constructor.  Looking at your change, it looks like this is the information
you’re logging now.  

I'll put some tests together using a default constructor on the drivers to see if I
can get this exception to be thrown.

I am getting this error as well in the firefox driver. It seems to be caused by one
of my sites waiting on a resource and never receiving it. So while it waits for that
page to give it it's resource, the other selenium calls after that fail with this error.
Eventually it gives up on that resource and all the calls that failed run in rapid
succession in firefox even though they already reported as failing. I have a small
test application that seems to reproduce the error if you are interested. I am on the
latest version of selenium.

Okay, this issue in general does not manifest itself in IE, or so it seems from the
comments. I'd like people to try with Firefox and Chrome, and the .NET bindings 2.40.0
(will be the next release at the time of this writing) or later, and see if this is
still happening.

I've seen fewer reports of this happening in Chrome since 2.35.0, so I need to know
if this is still an issue with the .NET bindings and a recent chromedriver.exe.

2.40.0 may have a fix for at least one of the issues that may cause this in Firefox.

If all you have to contribute to this issue is a "me too" or "when will this be fixed"
comment, at the very least, please provide the version of the .NET bindings and which
version of which browser you're encountering the issue in. It would be more helpful
in these cases to also have the exact text of the exception, since the change mentioned
in comment #33 gives more detail about what is actually happening.

Experiencing this issue in a 100% reproducible fashion with 2.38.0 and 2.39.0 against
FF 27.0

OpenQA.Selenium.WebDriverException: The HTTP request to the remote WebDriver server

timed out after 60 seconds. ---> System.Net.WebException: The operation has timed out

One of the failing tests basically looked like this (locking up when clicking the breadcrumb
on the 4th line):
  VerifyBreadcrumbNavigation(detailPage, BreadcrumbType.Category4, "Cats");
  VerifyBreadcrumbNavigation(null, BreadcrumbType.Category3, "Quadrupeds");
  VerifyBreadcrumbNavigation(null, BreadcrumbType.Category2, "Mammals");
  VerifyBreadcrumbNavigation(null, BreadcrumbType.Category1, "Pets");
  VerifyBreadcrumbNavigation(null, BreadcrumbType.Supplier, "Addimplower Holdings");

I tried reordering the breadcrumb navigations and no matter what I did it would always
fail on the 4th attempt no matter which breadcrumb it was doing at the time. I also
added longish sleeps (2000ms) all over the place thinking that maybe the driver couldn’t
handle so many navigation attempts. This also did nothing to mitigate the problem.

Just reporting back that I tried Selenium WebDriver bindings 2.40.0 and this solved
the problem for me - thank you. Looking at the change log, there is a commit from 1/31/2014
to remove console logging redirection: 

    "No longer redirecting console output for Firefox in .NET bindings."

Which is the workaround I used in http://stackoverflow.com/a/20181669/746754. So, it
all makes sense.
Anyways, this no longer happens for me, hopefully it will solve it for others too.
