Hello,

Thank you but already tried it... The problem is no to see the other players on Radmin VPN... I see them, I ping them, I've enstablished with them a TCP connection. But when I enter the game and I chose "multiplayer" I don't see anyone in my friend list to play with  

Hello,

Turn off firewall and antivirus and try again.
And try to change metric of Radmin VPN adapter. Firstly, set it to 1. If it didn`t help, set it to 1500 or to the max value (you can read more here https://www.raymond.cc/blog/choosing-which-connection-to-use-with-windows-routing-table-editor-gui/).

Thank you for the suggestions but I've already tried it cause I found this same suggestion on other topics. But still can't see people in game (the list of friends in the game is still empty)  

Hello,

Did your friends turn off firewall and antivirus and cnange metric too?

Yeah, sure... But I really added program exceptions on Windows Firewall instead of turned it off... I don't think it is a secure behaviour if you know what I mean

Hello,

You need to turn it off for some time to establish connection.

Hi,

Thank you so much, you were so helpful! I've encountered other problems but think is due to the bad developing of the game.
