Hi,
to start off, I’m still new to Mailcow & Docker.
Straight to the Problem:
Our Mailcow Server is currently on Nightly Build ‘89ed9147’. For external Authentication we’re using Keycloak connected to our local AD. Traffic also passes through a nginx reverse Proxy. After trying to update to the newest nightly version, the Login Page for our Server stays blank. All containers come back up without any Errors, apart from the SoGo Container which says “Waiting for Schema Update”, I’ve addded a part of the SoGo Logfile below.
Inspecting the Source Code of the Page also stays blank and the Developer Tools only show that its waiting for for server response. NGINX Logs also show nothing unusual.

Let me know, if I any other Logfiles, etc could be helpful.

Here is an outtake of othe SoGo Logs:
