Please Help! Failed To Join!

[Catalyst1945]

Okay, this happens to me 7/10 times when I invite someone or try and join them. I've been trying to sell gear all day on the market and I haven't had any luck because every time someone invites me to their dojo it just says "Failed to join session". How can I fix this?!?!

Does the internet analyzer in the options menu tell you there is anything wrong with your connection? It's a pretty common problem and it could be caused by a vast array of reasons, including distance and time zone differences.
