Does this bug reproduce in native VS Code?

No, VS Code on windows works.

Are you accessing code-server over a secure context?

• [x] I am using a secure context.

Notes

I try to use caddy provide a secure connection over https, but it dose not work yet.

[benz0li]

The use of the GitHub Copilot extension is restricted to Microsoft VS Code.

~Is this now enforced starting with 4.98? I'm using Github Copilot w/o issues in 4.96.x. and 4.97.1.~ so just did a quick minimal test and 4.98.2 with GH-cp 1.291.0 and GH-cp-chat 0.25.1 seems to be working for me

[code-asher]

I am not sure it is actually enforced, it more just means we are unable to provide debugging support since we cannot legally install it. 😢

[code-asher]

That said, maybe this is a different issue, with all the Extension host (Remote) is unresponsive logs. Will reopen. Are other extensions working?

[bilogic]

It's all greyed out for me

[RomanSonnik]

Any news about this? I also have grayed menu for copilot

[code-asher]

Are y'all also seeing Extension host (Remote) is unresponsive in the logs or something else?

[benz0li]

Are other extensions working?

Other extensions are working properly.

[longfei-zhang]

Same issue here: the Copilot menu is grayed out, so I'm using the Continue plugin for now.

Hi @longfei-zhang, I tried to install Continue plugin on code-server (last versions of both), and I can't login to continue.dev. Are you using local llm only ?

[Daxiongmao87]

Github Copilot is now open source, so I assume an issue should be created on that extension's repository, correct?

[benz0li]

@Daxiongmao87

Wow, big news. [...] Looks like they plan on integrating it into VS Code core, so there is likely nothing we will have to do, but we should keep an eye on this and test when it comes out.

Github Copilot adds a new icon ontop right of the command center. this is not visible in code-server. The icon below in status is now gone.

I installed Github Copilot Chat v0.29.0 on code-server v4.102.0-rc.1 and got the following error when I tried to login: command 'workbench.action.chat.triggerSetup' not found. Really confusing...

[vaibhav-dhawan]

I have copilot 1.343.1676 , copilot-chat 0.29.0 installed and working on v4.102.0-rc.1.

They're installed on the command line before code-server starts up: code-server --install-extension copilot-chat.vsix --force

which version of 0.29.0? they release a 0.30. which is again incompatible.. and the version i got 0.29.2025070102 -> shows error: Prerelease Version, not working.. and do you have the new copilot icon on the top bar with this version?

Even tried the last 0.28, same error:

Just plain 0.29.0 - but they do keep updating the extension. The trick is to install the target version of vscode matching the code-server version (102.0 in this case), then install the extensions there and check the version that gets installed in vscode, match the same on code-server

Oh also UI elements dont pop up, but you can still sign in to copilot/open chat etc via command menu

yes this is so sad. i really love my virtual development server in the net.. maybe its time to search for alternatives now.. this hassle with copilot sucks

checked, there is no 0.29.0 in archive: https://www.vsixhub.com/history/143611/

too bad..

It does work fine, you just have to use command menu/keyboard shortcuts instead of a nice copilot button to click:

Try this for copilot-chat and copilot

Ok tip from my side. since i updated to the new code-server release today and all was not working againg. export the extension_gallery to the store which normaly will sue you to their TOS and all works well. It seems the versions we get nowadays with all the tricks are "Prerelease Versions" with the nagging screen and not working.

i got it now running with: Identifier github.copilot-chat Version 0.30.1 Last Updated 2025-08-14, 13:47:41

and Identifier github.copilot Version 1.350.0 Last Updated 2025-08-14, 13:47:41

Both Version you wont get with all tricks (and vsix proxies) in the world. And they work now really smoothless with code-server.
