Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can

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.
This also likely isn’t an apache issue as other things on the same webserver function properly. Nextcloud is the only service not functioning correctly.
Is this the first time you’ve seen this error? (Y/N): N
