First i had error code : 4128, and then it got back to working, played 1 hour and then i got this error code.
Just bought the game for pc. Installed it and wanted to play online. Got the error code 103294 as a lot of gamers. Looked online for solutions, didn't find a clear answer.
Started from the end and after a couple of hours hard work i got it working. The error is because your NAT is not open in your router, and upnp is not set to on/active.
The second i figured that out the game connected and has worked ever since.
How you set the NAT / upnp on your router i cant tell, but it works.
