this is my first post. After searching around I haven’t been able to resolve my issue.
With turris omnia my Sonos system will not be able to update. I believe this never worked and my previous solution was to connect a different router with same ssid. The update worked then.
I am suspecting that this is a firewall issue.
I found this sonos faq article: https://support.sonos.com/s/article/688?language=en_US
It says that port 4444 tcp is required for System updates.
I have added this to the fire wall setup:
Sonos update: Any tcp - From any host in wan with source port 4444 To any router IP at port 4444 on this device - Accept input.
This did not help.
I am not very familiar with the firewall setup. I did not change many things from the system setup.
Can anybody help me?
