[bhavyaus]

Can you do F1 -> GitHub Copilot Chat Diagnostics and attach that output

[vs-code-engineering]

Thanks for creating this issue! We figured it's missing some basic information or in some other way doesn't follow our issue reporting guidelines. Please take the time to review these and update the issue.

Happy Coding!

[jascomp]

@etmoore I was having the same problem. Based on this thread, https://github.com/orgs/community/discussions/147055#discussioncomment-11606773, I updated WSL to 2.3.26 (Latest stable): https://github.com/microsoft/WSL/releases. I did that a couple of hours ago and have been using Copilot through WSL again without an issue.

@jascomp thanks for the tip, but I'm on a remote linux environment, not Windows.

Worth noting that when I reload VSCode, the first message or two will succeed, but then all subsequent messages hang.
Once it happens, Copilot auto-suggestions also stop appearing.

[chrmarti]

Please append the Copilot Chat and the Remote Extension Host log from when this happens. (F1 > Output: Show Output Channels... > GitHub Copilot Chat / Remote Extension Host)

Have you tried updating WSL as suggested in the discussion you linked to?

I'm working on a mac, connected to a remote linux (ubuntu) host via ssh, so don't think WSL applies to me, right? iiuc, that's for Windows.

[jascomp]

@chrmarti correct. WSL should not apply, but I do think it is a possible clue. Are you able to confirm the remote Linux machine has been updated?
