Nextcloud version (eg, 20.0.5):

Apache or nginx version (eg, Apache 2.4.25): 2.5.54
PHP version (eg, 7.4): 8.1.13

The issue you are facing: My server functions properly via the mobile apps and desktop app. However trying to access the server from a web browser returns a 503 service unavailable error. There doesn’t appear to be any logs related to this either which makes hunting for the issue frustrating.

Is this the first time you’ve seen this error? (Y/N): N
