I can't find rooms to play online

I downloaded the latest version of citra, but when I search for a public room, nothing comes out and my friend shows him the rooms and we download the same file.

Please give me a solution.

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.

Sounds like your windows firewall is blocking the connection? Did you allow internet access for Citra when you launched it?

I do not know, but I always start with “run as administrator” and before that I could play with my friend.
And today nothing appears, no room.
