Causes Of Error Code 004
Error Code 004 in League of Legends usually happens due to connection problems. The game cannot reach the server properly. This might be caused by a weak internet signal or network interruptions. Sometimes, the game files get corrupted or missing, which also triggers this error.
Other common causes include firewall or antivirus settings blocking the game. The system might think the game is unsafe and stop it from working. Server maintenance or high traffic can also cause this error. The servers may not respond well during those times.
Sometimes, outdated game clients or software bugs lead to Error Code 004. The game needs to be up to date to connect properly. Lastly, incorrect DNS settings or IP conflicts on your device might stop the connection.
Network Troubleshooting Steps
Check your internet connection first. Restart your modem or router to fix simple issues. Use a wired connection if possible, as it is more stable than Wi-Fi.
Close all background apps that use the internet. These can slow down your connection and cause errors.
Make sure your firewall or antivirus is not blocking League of Legends. Add the game to the trusted list.
Try changing DNS servers. Use public DNS like Google’s (8.8.8.8) or Cloudflare’s (1.1.1.1) for better speed.
Restart your computer to clear temporary issues. Then, open the game again.
Check if League of Legends servers are down by visiting their official status page.

If repair does not work, try running the launcher as an administrator. Right-click the launcher icon and choose “Run as administrator”. This gives the game extra permission to fix errors.
Another step is to check your internet connection. A weak connection can cause client errors. Use a wired connection if possible. Restart your router if needed.
