Edited by Demons: 11/28/2017 2:19:28 AMEdit: I spoke too soon. I thought it was working but actually even with opening incoming/outgoing ports as specified in the table it does not resolve the problem. I still need to disable windows firewall. [spoiler]Thank you -- I had assumed that allowing all TCP/UDP traffic by the .exe was as good as opening the ports (clearly not). It seems odd to me that out of the 6+ other people I know and play with I'm the only one that has to manually do this (and I have nothing exotic about my setup).[/spoiler]
