My girlfriend and I are trying to play on each other's worlds, but we continue to receive issues such as getting stuck at "Connecting to multiplayer game," "Locating server," and getting "Unable to connect." However, we are able to join the public servers such as CubeCraft. In addition, both of our servers have been made in the past few months. Both of our wifis also have strong connections to the Switch, so we do not think that it wifi is the problem. Why is it not letting us join each other's worlds?
