For a quick check of issues, the Lag Report is a great resource for measuring the ISP connection of the game servers. It's the best way to find the problems before you go to the game, so give it a try.
Before performing any troubleshooting steps, it is always best to check the current state of the League of Legends server status that you are trying to connect. List of servers are:
EU Nordic & East
Latin America North
Latin America South
Wireless connections will be difficult to troubleshoot due to constant interference from the environment and other radio signals. This often causes lags or some loss in the game. To remove this factor from our troubleshooting, we suggest you switch to a wired (Ethernet) connection if it is possible. If you have any issues contact League Support.
Firewalls work as they block both incoming and outgoing communications. Blocking INCOMING connections prevents "hackers" from accessing your computer, by handling a flaw in an Operating System or a commonly used software.
Firewalls are built by users to protect themselves. Outgoing connections are opened by apps running on your system. These are usually harmless like web browsers and instant messengers.
We have contacted many firewall manufacturers to identify League of Legends as a harmless application and add to exceptions automatically. Your firewall simply needs to update the firewall from the manufacturer to apply these exceptions.
The quickest and easiest way to solve your problem is to disable your firewalls. This is only for troubleshooting purposes.
Go to Control Panel
Click System and Security
Then go to Windows Firewall
Now Turn Windows Firewall on or off
Under each Network location, select the Turn off Windows Firewall option
It is important that you need to uninstall this third-party software in this step. Sometimes the firewalls still block your connections even if they are disabled. Once you found the reason for the issue, you can re-install and configure the firewalls properly to allow League of Legends network traffic.
For this step, you have to access your router configuration page. You can do this by typing the IP Address of your Default Gateway in your browser. If you are not sure what the IP address is or what is the login credentials for your router, there is a list available here. Please note that disabling the router firewall leaves you open to malicious scripts and software.
Here is a list of paths that you need to add to your firewall's exception list:
C:\Riot Games\League of Legends\LeagueClient.exe
C:\Riot Games\League of Legends\LeagueClientUx.exe
C:\Riot Games\League of Legends\LeagueClientUxRenderer.exe
C:\Riot Games\League of Legends\Game\League of Legends.exe
For this process:
Right-click on the firewall and go to Options or Settings.
Find a tab on Exceptions\Allowances\Applications.
Add all the four executables above. Give them "Full Access" or the equivalent setting.
The League of Legends launcher uses a server that has problems connecting to some Internet Service Provider’s default Domain Name System resolver. If your launcher doesn’t start downloading a patch, you try to change it to public DNS servers in your network settings. Most often, this only applies to users outside of the US.
We have two best tools for checking if packet loss occurs on your connection. The first one is our Lag Report tool, it quickly scans your connection and shows the score based on other players near you. This tool also shows a packet loss rating.
The second tool is the Connection Troubleshooting - Log Reader. Here, You can upload one of your logs from a previous game and check for packet loss, jitter, or ping of the game. This is tool will be help you big if you experienced a connection issue during your game and want further details.
If either of the tools reveals that you have packet loss, then your connection is losing data packets. If you experience anything like that then you need to contact your Internet Service Provider and troubleshoot it with them.
Always remember that some third-party applications also contribute to high buffering rates.
Examples of common applications which increase the buffering rate:
Youtube, Twitch, etc.
Sometimes the ports that need to accept connections from League of Legends servers are closed on a router by default. If that is the case, you need to forward them manually.
If you are connecting from a restricted network, like a college campus, you will need to provide the ports above to your network administrator so they can forward them to you. Please do a Riot Support ticket submit if your network administrator needs any additional information.
Please make sure that you are not using any VPN or a Proxy to connect to a League of Legends server, as they can cause many connection issues which will be difficult to fix. VPNs should be used to test your connection in very specific cases when advised by our Riot Game Support Technical Specialists.
