Can't play the game after 4.5 patch error 90002

[Auron359]

Ok firstly this issue is a little weird but all the same it has made the game unplayable for me so any and all help would be welcome. First let me explain the problem and what I have done/ discovered about the cause because its not normal at all.

-- Technical problem since patch 4.5--

When I create a new character and try to attune to ANY crystal be it the main one triggering the cut-scene or the smaller ones I get this error and the red disconnect symbol next to my name then booted from the game.
"Connection to the server has been lost" Error 90002

I can log back into the game and do whatever I like, I can take quests or just go out and kill monsters for hours ... BUT the second I try and attune to a crystal again i get error 90002 and booted from the game.

So in order for me to learn return / teleport or able to warp around any city I have to do the following

{ Attune - disconnect - reconnect - attune again - repeat on next crystal }

-- Current prognosis --

Investigating this odd issue has not been easy, I have already confirmed that it is not my network connection as playing on my laptop both with Wifi /wired does not suffer this crystal disconnect issue.
No the only time the game will do this is when I use my main PC, the specs are as follows :

Asus Rampage edition 10

I7 5960x
16GB DDR4 RAM
GTX EVGA 1080 FTW DT
128GB SSD / 1TB U.2 Drive.
Windows 10 - Fresh install along with up to date drivers and a fresh install of FFXIV and nothing else.

Is it a hardware issue ?
Well before 4.5 I had no problems playing the game not sure how hardware could be an issue now ?
It is also strange that FFXIV is the only game to claim a connection issue when no other online game that I play has a problem.
