I just tried a quick test to replicate this issue and wasn't able to, I was using lan connection not internet, so Ill see if I can work out a way to do that.

@WulftheNordicRanger - any other handy details you could provide? or if your still getting this error? I'm on MT5.3 current 3d_armor github build and no other mods except whats included with MTG base game.
