I dunno if this will be of any use for PC players unable to play online

It helped me, I was supposed to install teredo but the drivers list would not show up, i followed these instructions on https://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/how-to-install-teredo-tunneling-pseudo-interface/754c8f29-3a87-4e77-babd-a69c8910e17e and it seemed to fix the issue
