Dolphin randomly stopped connecting !

[tarzantan]

I've been playing my friends for months on dolphin netplay, I haven't changed any settings or the version I'm using. I moved a week ago, finally got my internet set up and now it says failed to connect everytime I try to join their game or the same thing on their end if they try to join mine. Please help me fix this I've deleted and installed dolphin like 5 times and I still have the same issue

If Dolphin and its settings haven't changed, it sounds like the variable is your connection and how you've set everything up. Try making sure your router, firewall, etc are correctly configured.
