Sometimes, in order to resolve your issue, our Tech dudes will ask you for some log files to learn more about your rig, network/connection or recent games. You can find out how to get the files that you need below.

Please bear in mind, that usually we only need one or two things to solve your issue, so there is no need to get every single file listed in this article :)

  • Network logs

    System logs

    League of Legends logs

    Additional info




    Hextech Repair Tool

    The Hextech Repair Tool (HRT) is a program that quickly compiles information from your game folder relevant to the issue at hand. Here’s how to use it:

    • Download and run the HRT.
    • Select 'Gather System & LoL Logs'
    • Locate the LoL Logs.zip generated to your desktop and attach the file to your next response on your ticket. If you haven't opened a ticket yet, you can do so here. Be sure to upload the zip file so we can look into your issue as quickly as possible.

    These tests will tell us exactly where the problem is occurring and give us a good insight on how to solve this problem.


    What is a Network Analysis?

    A Network Analysis will identify the properties behind your connection and provide insight into potential issues.


    To run an analysis:

    • 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, copy the link in the address bar (and NOT the contents of the page) of your browser (see example below).

    • Paste the link into your ticket. Please be careful about posting this log on the forums as it reveals your IP address to the public.

    Please note: If you are going to send us an email through Yahoo, please make sure to turn the Preview mode off. You can do so in either the "View" or "Settings" menus.


    Java Issues

    If your current Java version is out of date, you may need to get the most updated version of Java here: http://www.java.com/en/download/index.jsp

    Please bear in mind that Netalyzr no longer works in Google Chrome. You will need ot use Firefox or Internet Explorer instead.


    What is a Tracert?

    Tracert is an overview of the route your connection takes from your computer to our servers.


    Obtaining a Tracert:

    • Press the [Windows Key] (that is the key on the left side of the space bar, between ctrl and alt) + R
    • Type cmd in the search bar and click "Ok". You should now see a black window with white letters.
    • Highlight and copy the command based on the server you are trying to connect to:
      NA Server:
      (tracert 192.64.170.1) > "%USERPROFILE%\desktop\Tracert.txt"
      EUW Server:
      (tracert 185.40.65.1) > "%USERPROFILE%\desktop\Tracert.txt"
      or
      (tracert 162.249.72.1) > "%USERPROFILE%\desktop\Tracert.txt"
      EUNE Server:
      (tracert 31.186.224.42) > "%USERPROFILE%\desktop\Tracert.txt"
      or
      (tracert 95.172.65.100) > "%USERPROFILE%\desktop\Tracert.txt"
      OCE Server:
      (tracert 103.240.227.5) > "%USERPROFILE%\desktop\Tracert.txt"
      or
      (tracert 103.240.227.25) > "%USERPROFILE%\desktop\Tracert.txt"
    • Paste this into the cmd window (black box with white letters) by right clicking and selecting "Paste". Do not use the Ctrl+V shortcut as it will not work!
    • Depending on your connection, the trace may take 5-15 minutes to complete. A text file with the Tracert log will be created on your Desktop when it finishes.
    • Please check that the command ran properly - if Tracert.txt contains a single line, it did not run properly.
    • Attach Tracert.txt to a support ticket.

    Alternatively, you can download a free traceroute tool here. Once you run a trace to the IP address of the server that you are trying to connect to (listed above), please export the results as a .txt file (or make a screenshot) and attach it to the support ticket.


    What is a Process List?

    A process list shows all the software that is currently running on your PC. Some software might conflict with League of Legends and we can identify the common issues by looking over this list.


    Obtaining a Process List on Windows 7 and later versions:

    • Press the [Windows Key] (that is the key on the left side of the space bar, between ctrl and alt) + R
    • Type cmd in the search bar and click "Ok". You should now see a black window with white letters.

    • Download the tasklist.exe file.
    • Navigate to your Windows\System32 Folder.
    • Place tasklist.exe in that folder.
    • After that, run through the steps above for obtaining a process list.


    What is a NetworkInfo?

    This log provides us with information about your network adapter and your internal network configuration. It also shows us some basic information about your connection to the outside world.


    Obtaining NetworkInfo information

    • Press the [Windows Key] (that is the key on the left side of the space bar, between ctrl and alt) + R

There are two log files that we will need:

    Each file appears like this: [yyyy-mm-ddT15-40-03] _r3dlog.txt, where yyyy-mm-dd is the date of the match played.

    You can find them here:

    C:\Riot Games\League of Legends\Logs\Game - R3d Logs

    PVP.Net (commonly known as the "LoL Client") is our platform for in-game chat, along with your friend's list, profile page and matchmaking. Its logs contain all the information about errors you receive from the Login Screen through champion selection. This logging function ends when you enter a game after the champion select timer expires. One log is created per each play session, and each file will appear like this: LolClient.20110429.200043.log (The file name will include the time it was created - in this case: April 29th, 2011 at 20:00:43 (8PM)).

    Path Correction

    Occasionally, we may have our Players use Command Prompt commands to retrieve information for us to help them troubleshoot their issue and get back to the fields of justice. We are careful to issue these requests where appropriate, however, it should be noted that some systems cannot correctly execute a command because the path to the command is not properly set.

    For example, if the path to the ipconfig command is incorrectly set, you may receive an error similar to the following image:

    (Note that this command should actually be pulled from C:\Windows\System32\ipconfig.exe )

    If you are faced with this issue, please set the correct path for your Command Prompt by doing the following:

    • Log in with Administrator privileges
    • Click on the Start button
    • Right-click My Computer and select Properties
    • Go to Advanced system settings
    • Click Advanced tab
    • Click Environment Variables button.
    • In the System variables box, scroll down to Path and highlight it
    • Click the Edit button
    • In the Variable value box, add to the very beginning of the text C:\WINDOWS\system32;
    • Click OK three times.
    Note: Make sure you include the semicolon.

    After this, you should now be able to properly execute the ipconfig command. If you are having trouble with the instructions above and need to complete a command prompt to reply to us here in Player Support, please do not hesitate to ask the Support Specialist you are working with for further assistance.


    How to submit logs for the updated client for the open beta

    When we're helping you troubleshoot some of your updated client issues or are looking to improve the future of the client, there are times where your logs will be of great help to us in learning what may be going on.

    Keep in mind the updated client is still in beta, even with these logs there may not be a fix for your issues yet, but this info will help us improve the client going forward.

    How do I find my logs?

    You're going to want to go to your League of Legends folder (typically found somewhere like C:\Riot Games\League of Legends\) and open the "Logs" folder. There will be several folders inside the logs folder, with files inside.

    What do I do now that I know where my logs are?

    Now you are going to use your favorite zip tool (such as WinZip, 7Zip, etc.) to take all those folders and files into one compact .zip file. Once the files are all zipped together, you are going to attach the zip file to a support site ticket you can submit here [https://support.riotgames.com/hc/en-us/requests/new] for a technical issue. Be sure in the body of your ticket to specify this is an Updated Client related matter.
