Problems trying to connect to a room

someone who knows how to fix that ???

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.

The host of the room needs to set up port forwarding in their router settings. This is different per router set-up so they’ll have to google how to do so on their router.
