Step-by-Step Fixes for League of Legends Error Code 1001

1️⃣ Check Riot Server Status First

Before anything, verify if it's a widespread issue. Head to the official Riot status page.

2️⃣ Quick Restart Ritual

1. Close League of Legends completely (Task Manager > End riotclient.exe and LeagueClient.exe).
2. Restart your PC and router (unplug for 30 seconds).
3. Launch the client again. Boom—fixed for many! 🚀

3️⃣ Run as Administrator & Disable Fullscreen Optimizations

Right-click LeagueClient.exe > Properties > Compatibility > Run as admin + Disable fullscreen optimizations. This bypasses Windows restrictions causing Error Code 1001.

6️⃣ Switch DNS Servers

Google DNS often crushes ISP issues:

1. Control Panel > Network & Internet > Change adapter settings.
2. Right-click your connection > Properties > IPv4 > Use these DNS: 8.8.8.8 (primary), 8.8.4.4 (secondary).

7️⃣ Tame Firewall & Antivirus

Add exceptions for:

• LeagueClient.exe
• League of Legends.exe
• RiotClientServices.exe

Temporarily disable antivirus to test. Tools like Windows Defender or Norton are frequent culprits. 🛑

8️⃣ Ditch VPNs & Proxies

VPNs scramble your connection to Riot servers. Turn 'em off, or switch to a gaming-optimized one like ExitLag (test free trials). No VPN? Skip ahead!

9️⃣ Advanced: Clean Reinstall

Last resort for stubborn cases:

1. Uninstall via Control Panel.
2. Delete leftover folders: C:\Riot Games\League of Legends & %AppData%\Local\Riot Games.
3. Re-download from official site.

Fresh install = zero errors. 🎉
