I recently installed nextcloud on my OMV server and in the process I changed my web gui port for OMV to 81. I've done this long ago on my other OMV server with no issues.
However, today I realized I couldn't access the web gui at all. I couldn't even change the port in omv-firstaid as part of it would fail. I then tried to run service nginx start in the shell to see what was going on and got this:
```Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.

Has anyone run into this issue? I killed the containers for nextcloud/letsencrypt and removed the port forward from my router but still no help. I can access all portainer and container web GUIs just not the main OMV gui
