Cannot connect/host SSBM netplay matches...

[drjammy]

Hello. As of tonight, I am unable to host or connect to a netplay match in Super Smash Bros. Melee. Whenever I attempt to do so, I get this error message: "Timeout connecting to traversal server". This problem has just started occurring as I was playing last night. I don't know why this is happening, but any help would be appreciated!
