Connection Troubleshooting Guide (PC)

If you tackle this troubleshooting guide step-by-step, by the time you reach the end, you’ll have either leveled up to a Tech Expert and solved your problem or gotten much closer to helping our Support team help you do so. If you're still stuck after following the steps below, drop us a ticket using the button at the bottom of this page!

Switch to a Wired Connection

Wireless connections tend to be difficult to troubleshoot due to potential interference from the environment and other radio signals. This often causes lag spikes and/or packet loss in the game. In order to eliminate this factor from our troubleshooting, we recommend switching to a wired (Ethernet) connection whenever it is possible.

Do Not Use Proxies or VPN Connections

Make sure that you are not using a VPN or a Proxy to connect to a game 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.

Configure Your DNS

Changing to a Public Domain Name System

The game 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.

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.

Firewall Troubleshooting

Firewalls 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 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, the game and instant messengers, for example, open outgoing connections.

Based on that your firewall might be gatekeeping the fun, here’s how to give the game a VIP pass:

Updating Your Firewall

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

Visit your firewall provider's support site for the latest drivers and updates. Keep in mind, that some firewalls require an active subscription in order to receive the latest virus definition updates.

Disabling Your Windows Firewall

The quickest and easiest way to solve your problem is to temporarily uninstall and disable your firewalls.

  1. Press Windows Key 🪟
  2. Type Control Panel
  3. Press Enter
  4. Click on System and Security
  5. Click on Windows Firewall
  6. Click on Turn Windows Firewall on or off (You might need to provide the Administrator password at this step)
  7. Under each Network location, select the Turn off Windows Firewall option

⚠️Turning off your firewall should be for troubleshooting purposes only.

Adding Exceptions to Your Firewall Manually

Here is a list of executable paths that you will need to add to your firewall's exceptions list:

League of Legends
  • 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
  • C:\Riot Games\Riot Client\RiotClientServices.exe
  • C:\Program Files\Riot Vanguard\vgc.exe
  • C:\Program Files\Riot Vanguard\vgm.exe
VALORANT
  • C:\Riot Games\VALORANT\live\VALORANT.exe 
  • C:\Riot Games\VALORANT\live\ShooterGame\Binaries\Win64\VALORANT-Win64-Shipping.exe
  • C:\Riot Games\Riot Client\RiotClientServices.exe
  • C:\Program Files\Riot Vanguard\vgc.exe
  • C:\Program Files\Riot Vanguard\vgm.exe
Legends of Runeterra
  • C:\Riot Games\LoR\Live\Game\LoR.exe 
  • C:\Riot Games\Riot Client\RiotClientServices.exe
2XKO
  • C:\Riot Games\2XKO\Live\Lion.exe
  • C:\Program Files\Riot Vanguard\vgc.exe
  • C:\Program Files\Riot Vanguard\vgm.exe

 

There are many different types and versions of firewalls. It is outside the scope of this article to go into detail about how to configure each one. You may need to contact the manufacturer of your firewall in order to properly configure exceptions for the game.

Generally, this process requires three steps:

  1. Right-click on the firewall from your system tray
  2. Access Options or Settings
  3. Find a tab on Exceptions\Allowances\Applications
  4. Add each of the executables above. Be sure to give them Full Access or the equivalent setting.

Uninstalling third party firewalls

It is important that you fully uninstall these pieces of software during this step. Sometimes firewalls will still block connections even when they are disabled. Once you have found the source of the problem, you can re-install these firewalls and configure them to properly to allow for the game network traffic.

Port Forwarding

Why forward ports manually?

Sometimes the ports that need to accept connections from the game servers are closed by default on a router. If that is the case, you will need to forward them manually.

Connecting from a restricted network?

If you are connecting from a restricted network, such as a college campus, you will need to provide the ports below to your network administrator so they can forward them for you. Send us a ticket if your network administrator requires any additional information.

Step 1: Obtain your default gateway and internal IP address

Windows Mac OS
  1. Press the Windows Key 🪟 + R
  2. Type cmd
  3. Press Enter to open Windows Command Prompt
  4. In the command prompt, type ipconfig 
  5. Press Enter
  6. You should now see a list of information in front of you. Write down your Default Gateway and IPv4 address as you will need these in a later step.

Step 2: Reach out to your router manufacturer to configure port forwarding

Port forwarding can be tricky. It's best to reach out to your router's manufacturer on how to access your router's configuration page.

WindowsMac OS

List of ports to forward:

Game Client 5000 - 5500 UDP, 7000 - 8000 UDP
Patcher and Maestro 8393 - 8400 TCP
PVP.Net 2099 TCP
PVP.Net 5223 TCP
PVP.Net 5222 TCP
HTTP Connections 80 TCP
HTTPS Connections 443 TCP
Spectator Mode 8088 UDP and TCP
Game Voice Choose 50 Ports from 1024 - 65000
