Dolphin "Failed to Connect!" Traversal Netplay

My friends and I keep getting "Failed to Connect!" when we try to join one, and another. We both have the same Dolphin version, got the SC2 ISO from a same site, both have disabled memory cards, and have the same cheats. I've tried port forwarding 6262 and 2626 (both UDP) and allowed Dolphin in Windows Firewall (only Public). Does anyone else have a solution for this?

Also telling that I've never gotten "Failed to Connect!" before fixing the ports properly (it required my IP add so I input my Default Gateway. Now I changed it correctly to my IPv4 add). It just stays there and does nothing as if the Connect button doesn't work, until I fixed my ports that I started getting "Failed to Connect!".
