After Gitlab patching last evening (old version 14.10.2-ee.0) to 15.0.0-ee.0 we could not access our Git instance from the web but could still access through the Git interface. We rolled back to version 14.10.2-ee.0 and that got GitLab available from the web again as well. Please let us know of anyone else has seen this and if there is a fix for the issue.

This was the fix we applied to rectify the issue of accessing Gitlab from the web following version 15 update. “GitLab 15 specific changes | GitLab”

Thanks for sharing your solution
