I'm having the same problem man.. I can't see any servers at all. I really wish someone would help. I've uninstalled and installed Steam and ARMAIII countless times now.
Whenever I load ArmA III and click on the Multiplayer menu there are no servers. I've tried restarting my computer, signed out and back in to Steam, but still nothing.
If anyone has a solution, please help me.
Thank you!
