Squeezebox can't connect to Logitech Media Server running on PC

Debian 11, I have installed Logitech Media Server to use with Squeezebox player. Server is running on local IP Address: 192.168.10.xxx port 9000. I configured that address on my Squeezebox player, but it cann't connect to media server. I'm guessing that it might be caused by an ufw firewall running on Debian. I checked ufw status: sudo ufw status verbose Status: active Logging: on (low) Default: deny (incoming), allow (outgoing), disabled (routed) New profiles: skip To Action From -- ------ ---- 23/tcp ALLOW IN Anywhere 23/tcp (v6) ALLOW IN Anywhere (v6) I set rule for ufw firewall, but that not help: sudo ufw allow from 192.168.10.103 to any port 9000 here is Logitech Media Server Log File: [23-07-29 22:07:20.5102] main::init (377) Starting Logitech Media Server (v8.3.1, 1676361197, Fri 17 Feb 2023 06:37:09 AM CET) perl 5.032001 - x86_64-linux-gnu-thread-multi [23-07-29 22:07:20.5261] Slim::Utils::IPDetect::_init (138) Warning: Couldn't call connect() - falling back to 127.0.0.1 [23-07-29 22:07:25.6148] main::checkDataSource (1107) Warning: Schema updated or no media found in the database, initiating scan.

So, the answer is: to allow incoming connections to these ports: sudo ufw allow from IP_OF_YOUR_SQUEEZEBOX proto tcp to any port 9000,9090,3483
