METHOD 1
Go to https://github.com/chc/ut3-proxy/releases/tag/v0.1 and download the dll there then place it into your UT3 Binaries folder and that's it!.

IF YOU USED THE NO-GAMESPY PATCH BY EPIC MADE IN 2014 YOU MUST RE-DOWNLOAD THE OLD EXECUTABLE VIA STEAM INTEGRITY CHECK OR BY REINSTALLING THE GAME

METHOD 2
Go to https://ut3-ultimate.com/ and download the patch for the steam version and install it
and thats literally it!. You don't have to verify integrity with this patch as it replaces the actual UT3.exe file itself instead of being a dll hook patch that preserves your original executable

After the game shutdown most old accounts stopped working. Luckily you can still play the game its just that you need a new account. Simply pick any username you want and any password you want and you can still use your previous account's email if you are wondering. Once done you must fix the connecting forever bug. Simply just make a shortcut to UT3.exe on your desktop or somewhere you can easily find it

Simply zip up all of your game files in the folder you installed it in so that when the update comes out you can simply delete all of the files and replace it with your original install
