No, login in Fortnite is over 443 and it uses normal HTTPS.

It also uses HTTPs to load a lot of other data such as server data, friends list, chat etc.

Unreal Engine comes with a version of chromium built in which is used for many in game things like social tabs, news, and in game purchases these all work over HTTP/S.

Game data is sent over 5222 TCP.

Right, that's what I was guessing and am not sure why I was downvoted when everyone is confirming that contrarian's post doesn't really make sense since UDP isn't very relevant here.

Out of interest, do you know if the game data uses XMPP or if it just uses the same port?

[dogma1138]

5222 is pretty much used for all Epyc games I don’t think that I has anything to do with XMMP tho.

It does not. It's all based on the UE4 network stack.
