If you experience problems connecting to or successfully joining games of League of Legends, you may need to confirm you have the necessary access to certain ports on your network. It may be necessary to contact your network administrator to obtain this information.

Common Problems that can be resolved by port forwarding:

  • Inability to connect due to firewall errors.
  • Disconnections after the Victory/Defeat screens.
  • Difficulty joining chat.
  • Difficulty joining custom matches. 
  • Problems with a never-ending Matchmaking Queue or issues when trying to enter Champion Selection.
  • [RARE] Difficulty patching.
