Unable to Use Copilot and Copilot-Chat on Code-server 4.95.1 and Above

[sinlisin]

Hello Code-server community,

I'm facing difficulties with using Copilot and Copilot-Chat plugins on code-server version 4.95.1 and above. Despite installing multiple versions of these plugins, I'm unable to log in and use them, encountering an error message that reads
Invalid copilot token: missing token: 404
and

rejected with FetchError: No credentials were supplied, or the credentials were unavailable or inaccessible: No Kerberos credentials available (default cache: FILE:/tmp/krb5cc_3000) after 64.5982630001381ms

Are there any known solutions to address these login issues?
Or could someone recommend any specific versions of Copilot and Copilot-Chat plugins that have been verified to work with code-server 4.95.1 and above?
I would greatly appreciate any guidance or recommendations from those who have successfully navigated similar challenges.

Thank you!
