Cannot connect to a friend’s realm. I get the error code - 2124-5210 
it says there’s a problem with the server. My friend - on a computer - can connect. But another friend - on a switch - can’t connect. The error says it occurred approx: 12/7/21 at 10:35 am - however it’s 9:40 pm.

I have restarted my Nintendo switch, tried a different wifi, checked to see if there are any updates available, and I am still getting the issue. 

It happens when I log onto Minecraft on the switch but I can still play on my own worlds just not realms. It signs me out of my Microsoft account.

I've checked the Mojang status Twitter account and there is no information about an outage.
