Description Of Issue
Windows Defender Firewall somehow and sometimes blocks Quboz log-in in Roon. If the firewall is active, roon and all its parts work and you can play local music, but for no apparent reason the Qobuz connection is lost. It is not possible to login.
Solution: disable the Windows firewall completely and it works.
Of cours this not a solution; so which ports needs to be opened to have a stable Qobuz login via Roon? (Qobuz software itself works flawlessly on the same network.)
PS: The three Roon software pieces are allowed to communicate through the firewall (raatserver.exe, roonappliance.exe and RoonServer). But apparently that is not enough for Qobuz.
