Specifing port with hostname causes socket error

[sidey79]

What happened?

I get a socket error (getaddrinfo EAI_AGAIN) if i specify the env var "ZIGBEE2MQTT_CONFIG_SERIAL_PORT" with a hostname like this: tcp://:45108

If i add the ip address, then i get a connection
10.2.11.90:45108

Hostname resolution works from other containers in the same stack__

What did you expect to happen?

Network connection can be established via hostname

How to reproduce it (minimal and precise)

Specify a network connection SERIAL_PORT with a hostname and not an ip address
