I tried your Media Server.OVA and noticed that there is the version:
Server: mediaserver
Version: 10.7.2
as I am new with all this server stuff, I don't know if this is a docker or other installation ad there are surely different ways to get the latest version
I think I originally proposed this like 2 or 3 years ago, I can't find the thread but at one point my account on the forum got accidentally deleted so I'm guessing that's where it went.
