Avast firewall is blocking Sonos Controller

[laruelleb]

I have tried all the tips but nothing helps. I have set my network private, authorized the Sonos Controller on all ports without any success.
Really surprising as it works well when the firewall is deactivated.
I have also problems to access a Media Library based on a share on my Windows 10 PC !
Is there a solution ? Otherwise I have to switch to another Antivirus that is not blocking Sonos :-(

Set the Avast Firewall to private mode and reboot.
