To respond to Mega_Spud, I have not had any success in connecting at all. That specific error only occurs if I try to connect to Xbox Series S with my Switch, but my Switch hasn't been able to connect to any other console or person at all, usually resulting in an 'unable to connect to world' screen with no other details
I also do want to reiterate that my internet is working perfectly, and all consoles and devices (my Switch included) connect successfully to any other online multi-player experience and/or online store
