Troubleshooting Connection Issues



A connection issue is any event which adversely affects the connection between your computer and a League of Legends server. It might happen randomly during champion select, at the login screen or even during the match. Below you can find a list of common symptoms that are associated with connection issues:


Common Symptoms

You got an Attempting to reconnect message during the match



You received a firewall error message



You are experiencing consistent lag or lag spikes, generally having high ping in game. 



You received a "Failed to Connect" error message



You receive an "Unexpected" error message



You receive an "Unable to connect to the login queue" error message



You never reach champion select after queuing with your friends, even if they do

Click on the "Accept" button when a Match is found, however, you will be directed to lobby instead of champion select. Your friends will be able to view your presence in Champion Select screen, while you are still unable to enter Champion Select screen. You will be said to "dodge" the match because you are unable to choose a Champion in the champion select screen. 
 


 

Check Server Status

Before performing any troubleshooting steps, it's worth checking the current status of the League of Legends server that you are trying to connect to. 

Please refer to http://lol.garena.com or the Announcement section for latest update.

 

Firewall & Anti-Virus Programs Troubleshooting

Firewalls and Anti-Virus Programs serve two main purposes - they block both incoming and outgoing communications. Blocking INCOMING connections prevents external "hackers" from accessing your computer, usually by manipulating a flaw in an Operating System or a commonly used application.

Most firewalls and Anti-Virus programs are built to protect users from themselves. They do this by blocking OUTGOING connections. Outgoing connections are opened by applications running on your system. These are usually harmless; web browsers, League of Legends and instant messengers, for example, open outgoing connections.


Updating your Firewall

We have contacted a large number of firewall and anti-virus manufacturers to identify League of Legends as a harmless application and add exceptions for League of Legends automatically. It is possible that your firewall simply needs the latest update from the manufacturer to apply these exceptions.

Please note: Some firewalls and Anti-Virus programs require an active subscription in order to receive the latest virus definition updates.


Disabling IPV6

If the above steps did not help, please disable IPv6. The League of Legends client is designed to work with IPv4.

Click here - Microsoft has a wizard that will do this for you.

OR

You can disable it manually by following the steps below:

  • In the System Tray (bottom right of the screen), right click on your internet connection icon and selectOpen Network and Sharing Center
  • Click on the connection type under Connections (usually Local Area Connection) in the right part of the window
  • Click on Properties in the next window
  • Uncheck Internet Protocol Version 6 (TCP/IPv6)

There are also more advanced instructions in the Microsoft article linked above!

If you are looking to disable IPv6 on Windows 8 and 8.1, you can find instructions on how to do so here.

 

Configure your DNS

The League of Legends launcher uses server aliases that have problems connecting to some Internet Service Providers' default Domain Name System resolver. If your launcher never seems to start downloading a patch, you may want to change to public DNS servers in your network settings. Most often, this only applies to players outside of the US.

NOTE: Changing these settings can cause problems with your internet connection if you have specified network configurations for another purpose. Be prepared to revert to your old settings and save any information you are about to change.

Check for Packet Loss with Traceroute

Packet loss happens when one or more packets of data travelling across a computer network fail to reach their destination. 

Checking for Packet Loss

  • Download This
  • Extract and run it
  • Input "203.117.172.253" at the top left and click the "green play button".
  • Play your game as usual. 
  • The moment you face unstable ping issue, Alt + Tab to take a screenshot of the traceroute result. 
  • Save an image.
  • Post the image to a free image server like imgur.com, then paste us the picture.

Here are examples of common applications / causes which increase the buffering rate: 

  • Skype
  • Teamspeak
  • Ventrillo
  • Hamachi
  • Spotify
  • Anything that streams HD video content (i.e. Youtube, Twitch etc)
  • Torrent programs (i.e. uTorrent)
  • Active downloads (i.e Steam)

 

Do not use Proxies or VPN Connections

Please make sure that you are not using a VPN or a Proxy to connect to a League of Legends server, as they can cause a number of connection issues which will be impossible to resolve!

A VPN should only be used to test your connection routing path in very specific cases when advised by our Technical Specialists.
