I was running the server fine in OMV in a Docker Compose container. Then Docker-Compose did an update and I an no longer connect it on any Roon instance. I have since done a complete removal and reinstall (twice) of Roon Server using two different scripts. I get no errors starting the server but my app will not longer connect.

Have you confirmed the container is running without error? I don’t use OMV, but I’m certain you can check the service status and logs using the web interface or command line. Next, check that Roon server is reachable from the network, and that the correct ports are open for discovery.
Incidentally, I have moved your post to Tinkering since containers aren’t a supported configuration.
