Hello, I have posted a question some days before but it gets no response.
So I repost it after some finding of my question.
I tried to build a multiplayer game by following some tutorial videos. The server side create a session and then client side search sessions and join the session indexed 0. But the client cannot join the session after finding sessions (the code can be viewed on the link above, but the codes are same as the tutorial project.). I try to print out the error log using Event NetworkError and the client side prints out Lost Connection and Received Failure after the server created a sessions. It is the same when I play the tutorial project MultiplayerShootout.
One of my friends joins session successfully and my another friend cannot. Is it because of the setting of notebook or router?
