Fortnite error code 91, like all game errors apparently, does not provide any useful information for troubleshooting. Instead, you stayed to try to fix error 91 on your own. This problem is even more frustrating because several problems can cause the error code to appear.
How to fix error code 91 in Fortnite
Fortnite error code 91 occurs more frequently when trying to join a party. There is no definitive way to fix this, but there are a few things that have been shown to work:
- Make sure crossplay is active
- Restart your console / PC
- Restart your router / modem
- Check the Fortnite files
- Reinstall Fortnite
Make sure crossplay is active
You may see an error code 91 in Fortnite when trying to connect to someone on a different platform who has disabled cross-platform play. The first and easiest step to solving this problem is to make sure that all players trying to team up have cross-play.
To do this:
- Go to settings.
- Search for “Allow cross-platform parts”.
- Switch to “On”.
Restart console / PC
It is possible that a simple restart of the hardware will fix the problems. Sometimes, that’s all it takes to get rid of a 91 error in Fortnite.
Restart your router / modem
Sometimes, you need to restart your router and modem to get rid of this error. If the hardware restart does not work, restart the network devices later.
Check the Fortnite files
On PC, you can check the Fortnite installation files via the Epic Games Launcher. This will ensure that none of the games are corrupted. This is a procedure that will help you if your computer suddenly shuts down while you are playing.
Reinstall Fortnite
If you’re playing on console or mobile, you don’t have the ability to verify Fortnite files. Instead, you’ll have to uninstall and reinstall the entire game to make sure nothing is damaged.
