A connection issue is any event which adversely affects the connection between your computer and 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:
  • You got an attempting to reconnect message during the match
  • You received a firewall error message
  • You are experiencing consistent lag or lag spikes
  • You cannot download or patch the game
  • You are receiving a login error that is not related to your credentials
  • You received a disconnected from PVP.net error message
  • Your sound stutters in-game alot
  • You receive an unknown error message
  • You receive a maestro error message
  • You never reach champion select after queuing with your friends, even if they do
  • Your main client page is pitch black after logging in
CHECK SERVER STATUS AND SET REGION SETTINGS

Before performing any troubleshooting steps, it's worth checking the current status of League of Legends Philippines Server. Refer on the Official Website and Forum of LoL PH for Announcements.

(Garena+) At Settings hit the "Cog Wheel" found at lower left of G+ Messenger then at Region tab, choose Philippines:
(New Garena) At Settings hit the "Cog Wheel" found at upper right of Garena Client then at General tab, select Philippines

RESET WINSOCK
Winsock defines how a Windows network accesses TCP/IP services (i.e. Internet). The patcher needs to connect to our servers in order to download and apply the update, so it needs to be able to use the TCP/IP service effectively. It is designed to work with the default TCP/IP settings, so resetting them may resolve the issue.
  1. Press Start [Windows + R Key]
  2. Type and run cmd (Command Prompt)
  3. Type the following: netsh winsock reset
  4. Hit Enter Key
  5. Restart Computer and League of Legends
CONFIGURE INTERNET PROXY
At Control Panel Internet Options Connections Tab, select your connection and hit "Settings" and uncheck the following:

For Dial-Up/VPN Connections:
  1. Hit the Settings button
  2. Uncheck the box for: Automatically detect settings
  3. Uncheck the box for: Use automatic configuration script
  4. Uncheck the box for: Use a proxy server for your connection


For Local Area Network (Wired) Connections:

  1. Hit the LAN Settings button
  2. Uncheck the box for: Automatically detect settings
  3. Uncheck the box for: Use automatic configuration script
  4. Uncheck the box for: Use a proxy server for your connection
FIREWALL TROUBLESHOOTING
Firewalls serve two main purposes - they block both incoming and outgoing communications. Blocking incomingconnections 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, League of Legends and instant messengers, for example, open outgoing connections.
DISABLE YOUR WINDOWS FIREWALL
  • Click on Start
  • Click on Control Panel
  • Click on System and Security
  • Click on Windows Firewall
  • Click on Turn Windows Firewall on or off (You might need to provide the Administrator password at this step)
  • Under each Network location, select the Turn off Windows Firewall option
UPDATE YOUR FIREWALL
A large number of firewall manufacturers identifies 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.

UNINSTALL THIRD PARTY FIREWALL
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 allow League of Legends network traffic.

DISABLE ROUTER FIREWALL (NOT RECOMMENDED)
To disable your Router firewall, you will have to access your router configuration page. You can do this by typing the IP Address of your Default Gateway into the URL bar of your browser. If you are not sure what the Default Gateway IP address is or what the default login credentials are for your specific router. Please note that it is preferable to forward ports on your router, as disabling the router firwall leaves you vulnerable to malicious scripts and software.

ADD EXCEPTIONS TO FIREWALL MANUALLY
Here is a list of executable paths that you will need to add to your firewall's exception list:
  • C:\Program Files\GarenaPlus\ggdllhost.exe
  • C:\Program Files\GarenaPlus\Apps\lolph\Air\LolClient.exe
  • C:\Program Files\GarenaPlus\Apps\lolph\Game\League of Legends.exe
  • C:\Program Files\GarenaPlus\Apps\lolph\lol.exe
Additional Notes:
Unfortunately, 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 League of Legends.

Generally, this process requires three steps:
  • Right-click on the firewall from your system tray and access Options or Settings.
  • Find a tab on Exceptions\Allowances\Applications.
  • Add each of the four executable above. Be sure to give them "Full Access" or the equivalent setting.
DISABLE IPV6
League of Legends client is designed to work with IPv4. You may disable IPv6 to fully utilize IPv4.
You can disable it manually by following the steps below:
  • Find and open Network and Sharing Center (Control Panel or System Tray)
  • Click on the connection type or Connections (e.g. Local Area Connection) under HomeGroup
  • Click on Properties in the next window
  • Uncheck Internet Protocol Version 6 (TCP/IPv6) and hit OK

UPDATE SECURITY PROTOCOLS

  1. At Control Panel, open Internet Options
  2. Select Advanced (tab)
  3. Scroll down in the window to the Security section.
  4. Uncheck the boxes to disable SSL 2.0 and SSL 3.0.
  5. Check the boxes to enable TLS 1.0.
  6. Hit Apply.
  7. Restart League of Legends.

CONFIGURE DOMAIN NAME SYSTEM (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.
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.

PACKET LOSS AND PACKET BUFFERING
The best way to see if you have a packet loss issue is to run a Netalyzr on your connection. Here's how to do it: http://netalyzr.icsi.berkeley.edu/
  • Click on Start Analysis
  • Wait until the analysis completes. This may take several minutes.
  • Once the final result is displayed, check the result screen for packet loss.
  • If it has a yellow or a red light next to it, your connection is losing data packets before it reaches its final destination. Unfortunately, if that is the case you will need to contact your Internet Service Provider and troubleshoot it with them, as the quality of connection once it leaves your personal network depends largely on the service.
Please note: If your current Java version is out of date, you may need to get the most updated version of Java here: http://www.java.com/en/download/index.jsp

To check whether your connection has high packet buffering, please run the Netalyzr service on your connection. Here's how:
  • Click on this link: http://netalyzr.icsi.berkeley.edu/
  • Click on Start Analysis
  • Wait until the analysis completes. This may take several minutes.
  • Once the final result is displayed, check the result screen for packet buffering.
  • If it has a yellow or a red light next to it, your connection is experiencing high packet buffering.
Please bear in mind that some third-party applications can also contribute to high buffering rates.
Here are examples of common applications/causes which increase the buffering rate:
  • Skype
  • Spotify
  • Anything that streams HD video content (i.e. Youtube, BBTalk, etc.)
  • Torrent programs (i.e. uTorrent)
  • Active downloads (i.e Steam)

PORT FORWARDING
Sometimes the ports that need to accept connections from League of Legends servers are closed by default on a router. If that is the case, you will need to forward them manually.
  1. Obtain your Default Gateway and Internal IP Address:
    • At Start or [Windows Key] + R
    • Type and run cmd (Command Prompt)
    • Type ipconfig
    • Hit Enter
    • 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.
  2. Access your router's configuration page:
    • Open a web browser (Examples: Internet Explorer, Google Chrome, Firefox, etc.).
    • Place your Default Gateway into the URL Address bar.
    • You may be asked for a password and username. This will be different for each router. Try hitting Ok, but if this does not work the username is usually admin and the password is usually password.
    • Locate a page with one of these names: Port Forwarding, Virtual Servers, NAT or Applications
    • Port Triggering is not Port Forwarding. It is completely different.
    • If we have reached the proper screen you will notice that you can input several pieces of information.
      • The correct screen will ALWAYS have these: A SINGLE Port Range, Protocol and Local IP/IP Address/Computer.
      • The correct screen MAY have these: Application Name, A check box for enabled.
      • The correct screen should NEVER have: A second port range or an external IP field
    • Now you must create an entry for each of the port ranges listed on the previous page. It is very important that you put in the correct Port Range, Protocol (UDP or TCP) and Local IP.
      • LIST OF PORTS TO FORWARD
        • 5000 - 5500 UDP (League of Legends Game Client)
        • 8393 - 8400 TCP (Patcher and Maestro)
        • 2099 TCP (PVP.Net)
        • 5223 TCP (PVP.Net)
        • 5222 TCP (PVP.Net)
        • 80 TCP (HTTP Connections)
        • 443 TCP (HTTPS Connections)
        • 8088 UDP and TCP (Spectator Mode)
    • Note: If you are connecting from a restricted network, such a college campus, you will need to provide the ports above to your network administrator so they can forward them for you. Please send us a ticket if your network administrator requires any additional information.
RELEASE/RENEW IP AND DNS
For Windows Vista, Windows 7, Windows 8/8.1 and Windows 10
  • At Start or [Windows Key] + R
  • Type and run cmd (Command Prompt) - make sure it's running as administrator.
  • Type ipconfig /release and hit Enter.
  • Type ipconfig /renew and hit Enter.
  • Type ipconfig /flushdns and hit Enter.
  • Close the command prompt and attempt to make a connection.
For Windows XP
  • Click Start, then select Run and type cmd in the Run box. A command prompt window should open on screen.
  • Type ipconfig /release and hit Enter.
  • Type ipconfig /renew and hit Enter.
  • Type ipconfig /flushdns and hit Enter.
  • Close the command prompt and attempt to make a connection.

DISABLE IP HELPER

1. Open the Start Menu [Windows Key] and search "services" and click on Services.msc or Services:


2. Locate IP Helper, right-click it, and select Properties.
3. On the IP Helper Properties, Stop and select Startup type, and select Disable and hit Apply.

TERMINATING UNRECOGNIZED SERVICES
If you are encountering imminent Maestro Error regardless of having a stable connection, then follow this guide.

  1. At Task Manager, open the Services tab.
  2. Usually a Windows Service has its own unique coded name, if by instance a series of numbers (e.g. 6708336ed9480e7d04bd9b3c424e1590) identified as Windows Service is present on your Task Manager then Stop the Service by right-clicking on it. Note: The digits might not be identical with yours but there's only this kind of Service at Task Manager that should be stopped.
