The League of Legends Unanticipated Mistake with the Login Session issue is a common inconvenience in Riot Games’ well-known MOBA. This mistake prevents gamers from logging into their Riot Account and playing League of Legends online. Fortunately, there is a rather simple fix for the problem.

The League of Legends Unanticipated Mistake with the Login Session issue can be resolved in simply 3 easy steps:

The primary step is to hold Alt + F4 while clicking on the League of Legends customer and sign out. You should make sure to click “sign out” and not “exit” when performing this step.

The second step is to open the Task Supervisor by pushing either Ctrl + Shift + Esc or Ctrl + Alt + Delete. Once in Task Supervisor, close all instances of RiotClientServices.exe and LeagueofLegends.exe. To do this select each instance of the programs and click the “End job” button.

The last action is to resume the League of Legends or Riot Games! client and attempt logging in once again. If the mistake continues, repeat these steps and make certain to close the program KillerServiceNetwork.exe in Job Supervisor. This program might be restricting using your bandwidth for League of Legends and triggering you to disconnect.
