Your config.json is wrong. The software is telling you it can’t bind to an interface called demo.melina.ru as I suspect your computer doesn’t have a network interface with that name.
You can either set:
"pubOn": ["tcp://0.0.0.0:9505"],
To listen on all network interfaces, or you can set the IP address or name of one of your network interfaces to bind to just that one interface. If you want to bind to two or more interfaces, but not all, you can simply add to the pubOn array and we will bind to all the interfaces you say:
"pubOn": ["tcp://192.168.0.5:9505", "tcp://172.16.1.16:9505"],
or
"pubOn": ["tcp://eth0:9505", "tcp://eth2:9505"],
for example.
From the Player side, as long as tcp traffic going to demo.melna.ru port 9505 ends up getting to the interface XMR is listening on, then that is already configured correctly.
