I am continuing to have this issue after weeks of trying to figure out with minecraft support....they even sent me to nintendo, who sent me back to minecraft, they now sent me here. I get this error on my switch and cannot connect, i can connect via my xbox count ok. My little brother seems to have no issue connecting via his switch so im not sure why it seems like it's just me?
Tried visiting the FAQ again, tried checking internet connection. All seems ok on my end? Im not sure how to check or change the NAT. I have an xfinity router so if anyone is familiar with changing it on there please don't hesitate to reach out
