Netplay Traversal Server Desync

[sonicth033]

Hello. I seem to be having some issues with dolphin netplay. I just recentally attempted to play Sonic Gems Collection online with a friend, but our games kept desyncing. I hosted a Traversal server and we were both on the game, but our screens were completely off from each other in the race. I was wondering if there was any way to fix this desyncing problem whether it be port forwarding or something else, and I can provide any information needed to help solve the problem. Thanks in advance!
