epic games error 91

Error 91 in the Epic Games Launcher typically indicates a problem with the launcher's ability to connect to Epic's servers or a local issue with its installation. It often appears when trying to launch a game, update the launcher, or log in. Heres a structured troubleshooting guide to fix it, starting with the most common and easiest solutions. Primary Fixes (Try These First) Check Epic Games Server Status: Before anything else, visit the official Epic Games Status Page. If there's a yellow or red icon next to Epic Games Store, Launcher, or Friends & Chat, the issue is on their side. You just need to wait. Restart Your Computer & Network: Restart your PC. Power cycle your network: Unplug your router and modem for 60 seconds, then plug them back in. This clears your local network cache. Run the Epic Games Launcher as Administrator: Right-click the Epic Games Launcher shortcut. Select Run as administrator. If it works, you can set it to always run as admin by going to the shortcut's Properties > Compatibility tab. Disable VPN/Proxy and Antivirus Temporarily: VPN/Proxy: If you use one, disable it completely and try again. Epic's servers sometimes block VPN IP ranges. Antivirus/Firewall: Temporarily disable your third-party antivirus or firewall (including Windows Defender Firewall) to see if it's blocking the connection. Remember to re-enable it afterward. Advanced Troubleshooting If the primary fixes don't work, proceed with these steps. Clear the Epic Games Launcher's Web Cache This is the most effective fix for many launcher errors. Close the Epic Games Launcher completely (right-click its icon in the system tray and select Exit). Press Windows Key + R, type %localappdata%, and press Enter. Open the EpicGamesLauncher folder. Go into the Saved folder. Delete the webcache folder (or the webcache_443 folder if you see it). Restart the launcher. Flush DNS & Reset Network Corrupted DNS cache can cause connection issues. Open Command Prompt as Administrator. Type the following commands one by one, pressing Enter after each: ipconfig /release ipconfig /flushdns ipconfig /renew netsh winsock reset Restart your computer after the last command.
