When launching open.mp Launcher through the command-line, hostnames containing hyphens appear to be parsed incorrectly after being passed to the game/client.
Example hostname:
s2.gta-mp.cz
When launched with -h s2.gta-mp.cz -p 7777, the game appears to receive or display only:
s2.gta:7777
It looks like the -mp part of the hostname may be getting interpreted as another command-line argument somewhere after.
Tested on CachyOS with Proton, but this is most likely present in Windows versions too.
