Roon on QNAP - Nothing happen

After installing Roon Server on QNAP and the Apps on my PC and phones, they just freeze with the Roon logo. How do I set it up to my music library?

I guess there is a major issue at the moment but look here:

Christopher is already in contact with the Roon guys.

Maybe this issue also has an effect on your issue.
Many people are complaining about no library files anymore in Roon.
There is some way of work around but no solution so far.

see Roon Server = Stopped after update / QNAP [See staff post] - #76

FYI, I resolve the issue by changing Roon Server database to the same folder as my music library.

btw, which port is required by Roon Server? It won’t work once firewall is switched on.
