I just tried the GOG version with both wine-git and wine-5.18, both exhibit the same behavior. Creating a TCP/IP game doesn't work on both of them. It seems the game uses DirectPlay, so that would make sense.
Are you sure this worked on wine-5.18 and you didn't install any workarounds (i.e. winetricks directplay)?
Yes, I'm using the directplay installed with winetricks.
