How to record requests on latest with XMPP.

Thanks Lawin for this method.
Download LawinServerV1.
Go to the CloudStorage folder and open DefaultEngine.ini and change it to

[OnlineSubsystemMcp.Xmpp]
ServerAddr="ws://xmpp-service-prod.ol.epicgames.com"
Protocol=ws
bUseSSL=false

[OnlineSubsystemMcp.Xmpp Prod]
ServerAddr="ws://xmpp-service-prod.ol.epicgames.com"
Protocol=ws
bUseSSL=false

Put this into your fiddler script.

import Fiddler;

class Handlers
{
    static function OnBeforeRequest(oSession: Session) {
        if (oSession.hostname.StartsWith("xmpp-service")) 
        {
            oSession.oRequest.headers.UriScheme = "https";
        }
    }
}

Remember to change the mode to hybrid and make sure URL_HOST is right and URL_PORT is 3551 (default LawinServerV1 port).

Launching latest

Go to your Win64 folder of latest, replace FortniteClient-Win64-Shipping_BE.exe, FortniteClient-Win64-Shipping_EAC.exe, and FortniteClient-Win64-Shipping_EAC_EOS.exe with FortniteClient-Win64-Shipping.exe.

Launch fiddler, and when you get the error, inject Cobalt and then you should load in lobby a few seconds later.
