Login errors are widespread among online games and they can occur in various occasions, codes and classifications. Tackled in this post is a relevant issue on the League of Legends. If you’re playing this game on your Windows 10 computer and unable to get to the game due to some login issues, you can refer to this guide to troubleshoot the problem. Here’s how to deal with League of Legends login errors in Windows 10.
What causes League of Legends login errors?
Among the most well-known login errors encountered by many LOL players is the unexpected login session or unexpected error with login session. This error usually occurs when another instance of a League client gets stuck in the background.
Other known factors that can trigger relevant errors while attempting to login to an online game like League of Legends include network and server-related issues. This is usually when you’re attempting to login to your game while the server is currently unavailable or undergoing scheduled maintenance. Random software-related errors are also among the possible triggers. But the most obvious is when entering incorrect account credentials during login.
Troubleshooting League of Legends login errors in Windows 10
To eliminate software-related factors that have caused LOL login errors on a Windows computer, performing the following tweaks can help.
Before you go any further, restart your computer. This is recommended to clear out any existing system glitches that are causing random app malfunctions and errors. Restarting is also a simple way of clearing out any erratic cache and residual files from the system.
If the login error continues to show up on League of Legends after rebooting the system, then you may go ahead and try these workarounds.
First Solution: End All League of Legends Processes
If you’ve previously launched the game, it’s possible that it’s still running but got stuck in the background. As a result, the unexpected login session error occurs. To rule this out, force stop LOL processes through the Task Manager with these steps:
- Click the Windows icon to launch the Start menu and type Task Manager in the search field.
- Click to launch the Task Manager app from the search results.
- While on the Task Manager window, click to open the Processes tab.
- Find and click to select League of Legends in the list of running apps and services.
- Once selected, click the End now button at the bottom.
- Repeat the steps to end all other League of Legends processes you see in the Task Manager.
After ending all relevant processes, close the Task Manager and reload the game to see if the login error disappears. If the problem continues, try the next solution.
Second solution: End game client and killer service network processes.
- While on the LOL client, press Alt+F4 keys simultaneously then click Sign Out on the succeeding screen.
- After signing out, open the Task Manager.
- In the Task Manager, go to the Processes tab and then end all instances of your game client (example: RiotClientServices.exe) along with any other instances of LeagueofLegends.exe.
- If you see KillerServiceNetwork.exe on the list of processes, end it as well as this program might be prioritizing bandwidth to your online streams, resulting in a reduced bandwidth for League of Legends. When the LOL bandwidth is reduced, there is a higher chance for the game to be disconnected from the server and thus the unexpected login session error occurs.
After ending the said instances, close Task Manager then reopen the League of Legends client and retry logging.
Third solution: Quit LOL before the error appears.
One of the suggested tricks that has proven to work wonders on many LOL gamers is to quit the game before the error occurs. Here’s how they do it:
- Launch the League of Legends client as you normally do and log into your account.
- Shortly after logging into your LOL account (before the error prompt), press the X button to close the game. You will then be asked to confirm if you’d like to quit the game or log out.
- Select the option to Sign Out and then click Exit.
After a few moments, restart League of Legends and see if the unexpected login error is gone.
- Disable/disconnect VPN. If you’re using a VPN (Virtual Private Network) on your computer, try to disconnect it. Your VPN might be causing some problems to your computer system and eventually triggered the unexpected login session error while attempting to access your game.
- Disable antivirus/firewall. To rule out security-related issues from the underlying cause, try to disable your antivirus or firewall connections temporarily. Security tools can also trigger errors when security threats are perceived upon launching the game. If the error does not occur while the antivirus or firewall is disabled, then that’s an indication that the security tool is the culprit. This is when reconfiguring the security settings to set exceptions for both the game client and League of Legends game.
