How to Fix Fortnite ‘This Client is Not Compatible’ Error?
While logging into Fortnite I got a message this client is not compatible with the current server (or something like that) right in the center of the screen. Hadn’t logged into the game in weeks and decided to play a little, but alas.
Perhaps the only reliable solution to ‘This Client is Not Compatible’ in Fortnite is to completely reinstall the game. This way you will not only install the most current version of the game on your PC, which is guaranteed to solve the problem, but also get rid of potentially corrupted files. You can reinstall Fortnite in the Epic Games Launcher.
