Can’t join any Featured Server on Nintendo Switch (Undocked)

When you try to join a Featured Server on Nintendo Switch (Undocked) you constantly get a message saying “Disconnected from Server”. I have contacted these Server developers such as Cubecraft & InPvP but they don’t know the issue and neither do I. This has nothing to do with my Internet and it could be a Server breaking bug that will need to be fixed in an update very quickly. I repeat: The server developers don’t know the issue and I can’t fix it!
