Current behavior

this is still an issue. was able to reproduce using makeplane/plane-aio-commercial:v2.1.1 docker container. followed the https://developers.plane.so/self-hosting/methods/docker-aio guide.

Steps to reproduce

1. setup and deploy makeplane/plane-aio-commercial:v2.1.1 self hosted
2. enter /god-mode/ and attempt to setup github login
3. attempt to toggle on
4. go to workspace and see that GitHub oauth is not there

I also followed #8100's recommended instructions and manually set IS_GITHUB_ENABLED=1 and redeploy then it does show up, however the generated redirect URL to github is incorrect. I have my deployment behind a proxy and it currently attempts to use the private *.flycast domain name. the INTEGRATION_CALLBACK_BASE_URL does nothing regarding this too.
