NAT negotiation works with your router and connection.

I use the quick launcher to quickly launch RA3, I've selected no ip also, read all the thread and tried all the solutions, I am using 192.168 IP, I've removed firewall override.


Whenever I try to login I get an error "Cannot connect to backend servers", maybe this experimental launcher will solve this?

I don't think it will help.  This looks more like a connection problem. Please could you open Windows PowerShell (type PowerShell at the start menu) and in the window type and enter

Test-NetConnection peerchat.server.cnc-online.net -port 6667

then post the output in here.
