Problem to install Fortnite

Hello, I have a problem installing Fortnite on my PC. After downloading 4.36 GB, the download always stops, and it says there’s a connection issue. However, this only happens with Fortnite; when I install another game, it works without any problems. I’ve already restarted my router and PC. I uninstalled the game and tried reinstalling it, and I also completely reinstalled the Epic Games Launcher. I even tried running it as an administrator, but that didn’t work either. Do you have any tips or solutions?
