It was a problem with broadcast packet loss from the client to the server, depending on the situation... Client and server on a switch or on the same Wi-Fi, OK In all other situations, broadcast packets are lost even if they are on the same network 192.168.1/24...
I installed minidlna on a Linux Orange Pi PC 6.12.23-current-sunxi and also on an Orange Pi Zero, but it doesn't work; it doesn't appear in the client, on an LG Smart TV. On a Raspberry Pi, it does work; the configuration files are the same, and there are no network rules blocking any traffic... Any ideas what it could be?
