Thank you very much for this information.
I dug deeply in the network part and I found in debug mode some trace about a refresh related to IPv6.
The timestamp seemed to match with the Roon network reachability issues. So I decided to disable IPv6.
And so far it’s much better. I could use the application without a problem for 5 minutes in a row.
Thing I couldn’t do before.
So I will see, but I think I found the root cause.
The next step for me is to see if it was a normal IPv6 behavior which wasn’t handled correctly by Roon or this behavior is abnormal.
One last thing, may I suggest to change the Network reachability trace by something more relevant like network configuration changed.
