League of Legends Can’t Connect to Game? Fixes

If League of Legends won’t connect to a game, the cause is almost always one of a few fixable issues: a temporary server problem, a corrupted game file, a blocked port, or a network settings conflict. This guide walks you through the most common fixes, from the quickest checks to deeper troubleshooting, so you can get back to the Rift.

First Checks: Server Status and Restart

Before changing any settings, confirm whether the problem is on your side or Riot’s. The quickest way is to check the official Riot Games Service Status page (status.riotgames.com). If it shows an alert for League of Legends, wait it out — there’s nothing you can do locally. If the status is green, restart your client and your PC. A full restart clears temporary network and client glitches that often cause connection failures.

• Close the League client completely (check the system tray for the icon and right-click → Exit).
• Restart your router by unplugging it for 30 seconds, then plugging it back in.
• Reboot your computer, then relaunch the client.

If the problem persists after a fresh start, move on to the file and network checks below.

Repair the Game Client

A corrupted or outdated game file is a common cause of connection failures, especially after a patch. The Riot Client includes a repair tool that scans and replaces damaged files.

1. Open the Riot Client (the launcher that shows your profile and the Play button).
2. Click your profile icon (top-right) and select Settings.
3. In the General tab, scroll to the bottom and click Repair.
4. Confirm the repair. It may take 10–30 minutes depending on your connection and hard drive speed.

After the repair completes, try launching a game. If the repair fails or doesn’t help, you may need to fully uninstall and reinstall the client — but only after trying the network fixes below.

Check Your Firewall and Antivirus

Windows Firewall or third-party antivirus software can block League of Legends from connecting to the internet, especially after a game update. The client needs permission to communicate on specific ports, and a false positive can silently block it.

• Open Windows Defender Firewall → Allow an app or feature through Windows Defender Firewall.
• Look for League of Legends and Riot Client. If they’re missing, click Change settings → Allow another app and browse to their install locations (usually C:\Riot Games\League of Legends\LeagueClient.exe and C:\Riot Games\Riot Client\RiotClientServices.exe).
• Make sure both Private and Public boxes are checked for each.
• If you use a third-party antivirus, add the same .exe files to its exceptions list, or temporarily disable it to test.

After allowing the apps, restart the client and try again.

Flush DNS and Reset Network Settings

Your computer stores a cache of DNS (Domain Name System) lookups to speed up browsing. If that cache becomes corrupted, the client may fail to resolve Riot’s servers. Flushing the DNS cache is a safe, quick fix.

1. Open Command Prompt as Administrator (search “cmd”, right-click → Run as administrator).
2. Type ipconfig /flushdns and press Enter.
3. Type ipconfig /release, press Enter, then ipconfig /renew and press Enter.
4. Type netsh winsock reset and press Enter.
5. Restart your PC.

This resets your network stack without affecting your files or settings. If the issue is tied to a bad DNS entry or a corrupted socket, this should clear it.

Port Forwarding and VPNs

League of Legends uses specific ports for game traffic. While most home networks work without manual port forwarding, some routers or ISP configurations block them. If you’re on a strict NAT or behind a campus/work network, you may need to open ports or use a VPN.

• League of Legends uses TCP ports 2099, 5222, 5223, and UDP ports 5000–5500 (for voice and game data).
• If you’re on a home router, log into its admin page and forward these ports to your PC’s local IP address. The exact steps vary by router model.
• If you’re on a shared network (school, office), you likely can’t forward ports. A VPN can bypass restrictive firewalls — but be aware that using a VPN may violate your network’s terms, and it can increase latency.

If you’re using a VPN already, try disconnecting it. VPNs can cause routing issues that prevent the client from connecting to the game server, even if the website loads fine.

Common Error Messages and Their Meaning

League of Legends shows specific errors that point to the root cause. Here’s what the most common ones mean:

• “Unable to connect to the server” — The client can’t reach Riot’s login or game servers. Check server status, then your internet connection and firewall.
• “Connection failure” or “Unexpected error” — Often a corrupted game file or a DNS issue. Run the repair tool and flush DNS.
• “Firewall/antivirus blocking connection” — The client detected that a security program is blocking it. Add exceptions as described above.
• “You have been disconnected” — This can happen mid-game due to a drop in your internet connection, or a server-side hiccup. Check your connection and restart the client.

If you see a specific error code (like 004 or 014), search Riot’s support site for that exact code — they often have tailored fixes.

Frequently Asked Questions

Why does League of Legends connect to the client but not to the game?

This usually means your client can reach Riot’s login servers, but the game server (where the match runs) is unreachable. This is often due to a firewall blocking the game’s ports, a VPN interfering, or a regional server issue. Check your firewall exceptions, disable VPN, and verify server status.

Can I fix the “Unable to connect” error without reinstalling?

Yes, in most cases. Try the repair tool, flush DNS, and check firewall settings first. Reinstalling is the last resort because it’s time-consuming and often unnecessary if the issue is network-related.

Why does this happen after a patch?

Patches can alter game files, and sometimes the update doesn’t install cleanly, leaving corrupted files. Also, a new patch may trigger a false positive in antivirus software. Running the repair tool and adding exceptions usually fixes it.

Does a VPN help or hurt connection issues?

It depends. A VPN can bypass ISP throttling or blocked ports, but it can also add latency and cause routing problems. If you’re having connection issues, try without a VPN first. If you’re on a restricted network, a VPN might be the only solution, but expect higher ping.

How do I check if Riot’s servers are down?

Go to status.riotgames.com and look for League of Legends. It shows the current status of all regions. You can also check social media for widespread reports, but the official status page is the most reliable.
