Trading using citra in pokemon ultra sun

Enter a description of your issue here, in full detail.
I’m trying to trade with my friend and we both got our rokens and I created a room but he can’t join and I cant join any public rooms either. I keep getting the same message

In order for us to provide better support, we need to see the log generated by citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File

That error message is usually because the host of the room hasn’t set up port forwarding in their router settings for their port yet. This means that other people looking to connect can’t find an open port to join.

If you can’t join public rooms either, then that either means your router settings are disallowing you to do so, or you have a third party anti-virus software blocking the connection.
