The other day Jellyseerr stopped connecting to jellyfin. Now I fully uninstalled Jellyseerr with a fresh install to try and fix it. When going throug the setup page, I get Something went wrong while trying to sign in. and when I look at the jellyfin logs I get the attached error. Is this a jellyfin issue or a jellyseerr issue? How can I fix it?
