Use Wired Internet or Restart Internet Connection

If the server's Multiplayer Setting is already turned on but you still get the error, you might be having problems with connectivity.

If you're connected to the Internet using WiFi, switch to a wired connection to see if this fixes the problem. If you're already using a wired connection, restart your modem or router.
