Assistant: failed to sign in to copilot

[mdborg]

When i try to sign in to github copilot, it seems like the login process never start, and after a while, i just get a timeout error.
Positron has no issues connecting to github for the github pull request extension.
Has anyone experienced this or have any idea how to solve it?

Hi mdborg, sorry that you're having issues with signing in. Are you behind a proxy? The normal flow is to show a prompt that you will have authorize Positron and a dialog will show a code to use to complete the authorization process. Do you get the dialog for that?

Im not getting the code before I get the timeout error. Edit: I only get the code in positron when i sign in to the GitHub pull request extension. I also tried manually installing the GitHub copilot vs code extension via VSIX, which also correctly gives me a code and opens my browser.

No, I'm afraid I can't acces the internet without VPN.

I found a way to check without VPN (on company network) and it didn't make any difference. There still might be a proxy though.

Can you export your logs from the Output view? I think this would be a good time to open an issue for your problem.

GitHub Copilot Language Server.log
Extension Host.log
Full output.log
Window.log
Main.log
@timtmok here is the output log from a new session where I had reset all settings to default. All i did was enable positron assistant, then configure language model providers -> github copilot -> sign in. I also added the output I found most relevant as separate files.

@mdborg Nothing in the logs stand out to me but where did you get the Github Copilot VSIX file to manually install? I suggest removing that and clearing the Positron state (https://positron.posit.co/troubleshooting.html#resetting-positron). The Copilot extension is actually forked from the original to work with Positron since it needs a few things done to work with Assistant.

I actually have a friend who has this same issue...
