I'm getting:
Docker Application Sonarr_lnxio, Container Port 8989 not found or changed on installed application
Docker Application Sonarr_lnxio is currently set up to run in host mode
Docker Application NZBGet_lnxio, Container Port 6789 not found or changed on installed application
Docker Application NZBGet_lnxio is currently set up to run in host mode
Docker Application binhex-couchpotato, Container Port 5050 not found or changed on installed application
Docker Application binhex-couchpotato is currently set up to run in host mode
If I change to Bridge mode, both warnings go away, but the fact is, in host mode, the port works correctly - I use <address>:5050 on my local net to get to couchpotato and it works fine.
Not a big deal, but seems kind of wierd.
