Players can't find the Steam servers.

Hello. I am a programmer of the game “Peekaboo”.
We use Steam as the master server. Each player can create a server as a host.
Everything works well, but players are constantly complaining that they can not find the server. Constantly plays 10-50 players.
I checked this information and realized that it depends on the chosen steam download region. Therefore a player from Asia does not see the server from Europe.
How can this be corrected? We have a lot of negativity from this.
Thank you so much.
P.S. To anyone who can help, I will give the key of the game :slight_smile:
Sorry for my English, I’m not a native speaker.

Still relevant.
