I got the following message with pyradio server.
When i, for the first time, start Pyradio [localhost or lan] everything works fine with the server.
$ lsof -i4
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
pyradio 4534 vogel 4u IPv4 35649 0t0 TCP localhost:distinct32 (LISTEN)
pyradio 4534 vogel 5u IPv4 38000 0t0 TCP localhost:distinct32->localhost:55852 (CLOSE_WAIT)
mpv 4556 vogel 12u IPv4 51360 0t0 TCP vogel-box:53424->streamer-london2.radio.co:http (ESTABLISHED)
But …
When i exit Pyradio. The server connection keeps running.
$ lsof -i4
