I encountered this issue when first trying to use "edit from my PC"; applying the Microsoft procedure to update the prototols indeed solved it. The process requires two steps (1. install, 2. correct registry)
Need to apply that update on all clients supposed to use the functionality

Online edition is working again on Ubuntu 18 however you must :

after install restart your brower AND deactivate and re-activate the Firefox extension

@mahrouqi Dear Badar, Did you manage to solve user login using AD ?

Best,

In fact the current image GoFAST 3.5.2 OVA has been created in French locales.

So to type the initial password in console mode you must set your keyboard to French.
It is possible after login to set back to US keyboard :
localectl set-keymap us

We will try in the future to avoid this issue perhaps by creating 2 images or another mean.
