[sasikiran1998]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version:
• OS Version:

Steps to Reproduce:

1.XHR failed 2.Not able to see extensions. 3.Every time getting error like " We cannot connect to the extensions marketplace at this time. "

Can you please open dev tools console and see if there are errors related to this? You can run the command Toggle Developer Tools from command pallette to open developer tools.

[sasikiran1998]

Could You specify what to open more clearly, I am using Windows 10. I did not get where to open dev tools and all. So suggestions are readily accepted..

And for more info: 1.Whenever VS Code is opened, it never shows the extensions. 2.If I try to download from internet also, it always shows message as XHR failed. 3.This issue is not resolved even if i try to uninstall and reinstall VS code again and again. 4.Whever is done, the extensions are never visible and will always throws message as " We cannot connect to the extensions marketplace at this time".

Same issue here, before the last update it worked fine and I could browse extensions. I've tried allowing all connections inbound & outbound through Windows Firewall but still nothing.

Edit: Manually installing an extension through command line worked. Example: codium --install-extension icrawl.discord-vscode

[sasikiran1998]

Ok .. I wil try and update ..

[sandy081]

To open developer tools, please do following:

• Press F1 - this opens command pallette
• Type Developer: Toggle Developer Tools and select that command
• It opens the developer tools console
• Try to repro the issue and see if there are any errors in the console

@Akitakek I do not think VS Code and Codium are same, so if you are seeing issues with Codium, please file issues against that product.

@deepak1556 Tunnel Connection Failed - electron / chromium related ?

[sasikiran1998]

wat needs to be done after i open developer tools, there are many errors and warnings.. suggest me how wil i get the extensions activated in my vs code..

[SinTan1729]

I'm also having the same error in Manjaro.

[deepak1556]

ERR_TUNNEL_CONNECTION_FAILED indicates they have a proxy server configured and it either rejects request to the marketplace or some other error at the proxy layer.

@sasikiran1998 couple of things to confirm,

Are you able to access https://marketplace.visualstudio.com/_apis/public/gallery/publishers/ms-vscode-remote/vsextensions/remote-containers/0.163.2/vspackage from your system browser ? If it works, then try the following. If not then please check your proxy blocks connections to https://marketplace.visualstudio.com/

1) Launch with code --user-data-dir <dir> (fill some absolute value for <dir>) and check if extension search works 2)

• Launch with code --log-net-log=<dir>/netlog.json
• Perform the extension search
• Quit the application
• Attach the netlog.json file generated at <dir>

[sasikiran1998]

I have tried your expressions and got the result as mentioned. But this did not solve my issue of getting the extensions, please take a look and specify me how to get the extensions activated.

[deepak1556]

Are you able to access https://marketplace.visualstudio.com/_apis/public/gallery/publishers/ms-vscode-remote/vsextensions/remote-containers/0.163.2/vspackage from your system browser ? If not then please check your proxy blocks connections to https://marketplace.visualstudio.com/

Did you try this ?

Also can you attach the generated netlog.json file

[sasikiran1998]

i tried to access the link : https://marketplace.visualstudio.com/_apis/public/gallery/publishers/ms-vscode-remote/vsextensions/remote-containers/0.163.2/vspackage

and a VSIX file downloaded.

[deepak1556]

Thanks for testing, can you provide the netlog file for further debugging.

[sasikiran1998]

the netlog file is empty I am using Windows 10 No proxy I am on Jio4G wifi network

[deepak1556]

Based on https://github.com/microsoft/vscode/issues/128229#issuecomment-883974825 the path you have specified is incorrect, it should be code.cmd --log-net-log="C:\Users\sasi\AppData\Local\Programs\Microsoft VS Code\netlog.json"

[sasikiran1998]

I am getting like tis..

what needs to be done next ?

[sasikiran1998]

Again i am getting the same error:

[deepak1556]

Please share a screen recording of what you tried including the commands used to launch the app, you may find https://gifcap.dev helpful as a browser-based gif recording tool.

[sasikiran1998]

Plz find the attached video glimpse, and after even after i relaunch the vs code app, the extensions are not working

[deepak1556]

The path should be enclosed in quotes to be parsed correctly. Please follow the steps below to get the log file

• Launch with code.cmd --log-net-log="C:\Users\sasi\AppData\Local\Programs\Microsoft VS Code\netlog.json"
• Perform extension search (this step should fail which is expected)
• Quit the application
• Attach netlog.json file from the path C:\Users\sasi\AppData\Local\Programs\Microsoft VS Code\

These steps will not fix the issue but will provide better logging to understand the issue.

[sasikiran1998]

I have executed the above said, as the netlog.json file format is not supported here, i have mailed u the file.. what to do next??

[deepak1556]

Thanks for the log, it shows that a proxy server has been configured.

You might want to disable Automatic Proxy setup under your system network settings. Closing as issue is not from vscode.

[sasikiran1998]

Even if i have disabled the proxy, i am getting the same issue :

[deepak1556]

Can you start with code --no-proxy-server and check.

[sasikiran1998]

Still the problem persists

[deepak1556]

Please attach a new netlog by starting with code.cmd --no-proxy-server --log-net-log="C:\Users\sasi\AppData\Local\Programs\Microsoft VS Code\netlog.json"

[sasikiran1998]

Should i delete the previous one?

[sasikiran1998]

[deepak1556]

Should i delete the previous one?

No it will be overwritten. You can follow the same steps as https://github.com/microsoft/vscode/issues/128229#issuecomment-885186811 with added --no-proxy-server for the first step. You can zip the netlog.json file and upload to this issue.

[sasikiran1998]

netlog.zip

[sasikiran1998]

netlog.zip

[deepak1556]

Can you print the values of echo %http_proxy% and echo %https_proxy% from the command prompt. Also can you check if "http.proxy" setting in vscode is not configured ?

Netlog shows you are still using a proxy,

t=1044 [st=  1]   +PROXY_RESOLUTION_SERVICE  [dt=0]
t=1044 [st=  1]      PROXY_RESOLUTION_SERVICE_RESOLVED_PROXY_LIST
                     --> pac_string = "PROXY www.google.com:80"

[sasikiran1998]

[sasikiran1998]

The extensions are activated. Thus the issue is closed..

[sasikiran1998]

Thanks @deepak1556 for solving this issue
