Can it connect to a server using IP address instead of domain name?

[lsahnicne]

I've set up a VPN server and generated an .ovpn file for the client.
That OVPN server doesn't have a domain name but has a public IP address. The .ovpn file has a line like this:
"
...
client
remote 12.345.67.89 12345 udp
auth-nocache
...
"

.ovpn file imported into an app successfully, the server address field includes an IP address.
But when I try to connect to the server, the app tries to resolve an IP address as a domain name and it's log has a repeating message like this:
"RESOLVE: Cannot resolve host address: 12.345.67.89:12345 (servname not supported for ai_socktype)"

Is there a setting or other way to tell an app that the server address field contains an IP address and not the domain name?

Please include a full log. Or instruction how to reproduce this. THis is not something that is known bug and has happend before.

Apparently the cause of issue was that I tried to use a port outside of 1-65535 range.
Tried it with a few different port numbers like that and it outputs the same message, so that's a reproduction instruction.
