Let me explain how to fix League of Legends reconnect bug with several proven solutions.
I'll start with the most effective method and work through other options.
The most reliable fix comes from uninstalling Citrix Workspace. Many players found this program conflicts with League, causing reconnect loops.
Remove it completely from your computer through Windows Control Panel.
Try watching a replay first if you can't connect to games. Download and watch any available replay, then start the tutorial or practice tool. This sequence often breaks the reconnect loop and lets you play normal games again.
Running League as administrator helps too. Right-click the League client shortcut, select Properties, and check "Run as administrator." This gives the game proper permissions to connect.
Update your graphics drivers and Windows next. Old drivers or missing Windows updates can cause connection problems. Install all available updates before trying to play again.
The firewall might block League. Temporarily disable your firewall to test if it causes the problem. If this fixes the issue, add League to your firewall's allowed programs instead of leaving it disabled.
Clean boot Windows if problems persist. This starts Windows without extra programs that might interfere with League. Search online for "Windows clean boot" instructions specific to your version.
I recommend trying these solutions in order.
Start with removing Citrix Workspace since it causes most reconnect problems. Then work through the other fixes if needed.
Remember to restart your computer after trying each solution. This guarantees all changes take full effect before testing the game again.
