Setup

Prerequisites

• Download and install NodeJS
• Download and install .NET 6 Desktop Runtime
• Download and install Fiddler Classic

Proxy setup

Even though proxy is included in the launcher, it can cause issues. I recommend using Fiddler.

Fiddler setup

• Make sure you have installed Fiddler from the above link,
• Open Fiddler and click on the FiddlerScript tab
• Delete everything that is there and paste this script in:

import System;
import System.Web;
import System.Windows.Forms;
import Fiddler;

class Handlers
{ 
    static function OnBeforeRequest(oSession: Session) {
        if (oSession.hostname.Contains("ol.epicgames.com")) {
            if (oSession.HTTPMethodIs("CONNECT"))
            {
                oSession["x-replywithtunnel"] = "FortniteTunnel";
                return;
            }
            oSession.fullUrl = "http://localhost:3551" + oSession.PathAndQuery;
        }
    }
}
