League of Legends errors and common problems

Can't log in: Wrong region, clock out of sync or DNS

Means

You get an error on the login screen that has nothing to do with your password, or the login times out. Riot points to the wrong region, a server problem, a PC clock that is out of sync, or DNS trouble with your provider.

First step

Check that the client is set to the region where your account lives. All steps

Attempting to reconnect: Connection drops during a match

Means

The Attempting to Reconnect box appears when the connection is badly disrupted and the game is trying to catch up on missing data. Your champion may freeze while everything else keeps going.

First step

Check the server status page and ask your provider whether there is a problem in your area. All steps

Lag and low FPS: Weak hardware, heavy settings or old drivers

Means

Riot says lag usually comes from a PC below the requirements, graphics settings set too high, old graphics drivers, overheating, or a busy network.

First step

Check that your PC meets the minimum system requirements. All steps

Won't start after champ select: Security software or old settings block the game

Means

Champion select ends but the loading screen never starts. Riot points to background programs, security software, old graphics drivers, compatibility mode or damaged files.

First step

Do a clean boot to rule out background programs. All steps

Black screen: Graphics, firewall or game files get in the way
