Fortnite error code 91, like seemingly all game errors, doesn’t give you any useful information for troubleshooting. Instead, you’re left to try and fix error 91 on your own. This issue is even more frustrating because several problems can cause the error code to pop up.
How to fix error code 91 in Fortnite
Fortnite error code 91 occurs most frequently when you’re trying to join a party. There’s no definitive way to fix this issue, but there are a few things that have been proven to work:
- Make sure cross-play is turned on
- Restart your console/PC
- Restart your router/modem
- Verify Fortnite files
- Reinstall Fortnite
Make sure cross-play is turned on
You may get an error code 91 in Fortnite when trying to connect to someone on a different platform that has cross-platform play turned off. The first, and easiest step to troubleshooting this issue is to make sure all players trying to squad up have cross-play on.
To do this:
- Go to settings.
- Look for “Allow Cross-Platform Parties.”
- Switch it to “On.”
It’s possible that a simple restart of your hardware will clear issues up. Sometimes, that’s all it takes to clear an error 91 in Fortnite.
Restart your router/modem
Sometimes, it’s a restart of your router and modem that’s required to clear up this error. If restarting your hardware doesn’t work, reboot your network devices next.
Verify Fortnite files
On PC, you can verify your Fortnite install files through the Epic Games Launcher. This will ensure none of the game is corrupted. This is a procedure that will help if your computer suddenly shuts down while you’re playing the game.
If you’re playing on console or mobile, you don’t have the option to verify Fortnite‘s files. Instead, you’ll need to uninstall and reinstall the whole game to ensure nothing is corrupted.
