  3. Launch the client again. Boomโ€”fixed for many! ๐Ÿš€

6๏ธโƒฃ 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).

7๏ธโƒฃ 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. ๐Ÿ›‘

8๏ธโƒฃ 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!
