Description of Issue
After updating my Roon Server to Build 880 I couldn’t connect to the server. Not from any devices. After checking the logs, I realized that the Linux firewall was blocking some ports. After opening them with:
sudo ufw allow 5353
sudo ufw allow 9330
sudo ufw allow 9332
Now I can connect again. I don’t know if you’ve changed any port allocation, but if anyone else has the same problem, this could be it.
