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
