I've seen many issues about the same error but with a different code 403, where I am getting code 401. The problem has been happening for a while, and I always assumed it will eventually get fixed with an update.

When this happens, I need to restart VSCode to get things working as normal again. This isn't that big of a deal with Copilot Chat since it will throw an error directly, but I don't always notice when the AI-assisted code completions/suggestions stop working.

I am not exactly sure what causes this, but I think it happens when I leave VSCode unattended for a while (30 minutes maybe?).

I have met the same problem...

I couldn't manage to include diagnostics in my original post because VSCode crashed (for unrelated reasons), but today I got the same issue so here is the output when Copilot and VSCode are in 401 state, so to speak:

bumped into the same issue

Same issue here. Some times the chat section looks empty and other times the chat throws 401 error. The section gets unresponsive. This feature is not working Looks like the autocompletion is working fine This is happening despite authentication was successful

[luismatias90]

I was having this problem, and for me, I just enabled the "Copilot Chat in the IDE" option in the GitHub Copilot policies settings. It worked :)

Oh, that was the problem! Thanks a lot for the suggestion!

Do I need to have an organization in my github account to enable this setting? I am not exactly sure where this setting is enabled from.

I am using Copilot Individual, not business or enterprise, so I'm not sure this fix is applicable to me.

You need to go to: Organization Settings -> Copilot->polices!

[virtuallyunknown]

Appreciate your help @dezguell, but I am not a member of any organizations.

On this page all I have is this, so I don't have the option to change any organization settings:

@TylerLeonhardt this is still happening, and it's still very annoying having to restart VSCode every time. Any chance someone can look into it?

I'm only tagging you because it says you were assigned for this issue, but we haven't heard any official response so far. Thanks.

Hi @virtuallyunknown sorry for the delay here. I have done some work recently to improve the experience. I'm curious if it fixes the issue you're seeing.

You can try out the changes in the Insiders build of VS Code and then get the GitHub Copilot Chat pre-release version. Just go to the Extension Pane and it should allow you to install the pre-release.

Can you grab those and let me know if that helps?

I have switched to the pre-release version of the extension and I will let you know if the issue occurs again.

As for the insiders build of VSCode itself, these updates are going to make it into the stable release next month, is that correct? I prefer to just wait until then to test, as switching from normal to insiders probably requires some setup and time investment, and I depend on my code editor for work.

Anyway, when I have some useful information I will let you know!

Greetings again @TylerLeonhardt. I thought this was finally fixed because I enjoyed a period without the issue happening, but unfortunately it happened again just now.

As seen, the chat is giving errors, and editor code suggestions stopped appearing as well. Highlighting a code block and pressing Ctrl+Enter also just gives 0 suggestions.

Having the same problem here, although I have already enabled the policies.

EDIT: I updated vscode version and it started working again.

[TylerLeonhardt]

We've just released VS Code 1.92 & Copilot Chat 0.18. (should be available in a moment if it's not already)

1. Can you try with that? It has some auth related fixes that I made.
2. If that doesn't work, can you grab the pre-release version of Copilot Chat (0.19.x)? I've pretty much re-wrote the whole auth stack in it...
