How do I fix this

I get this error code when I try to connect sessions to Fortnite. I don’t know how to fix this. I need it to connect to finish my project. I contacted them and they said I have to come here.

Failed to find a server through matchmaking: Error: errors.com.epicgames.fortnite.invalid_region
