Cannot finalize setup of Azure migrate appliance (Powershell command)

Question

Appliance was set up correctly, yet once the azure migrate appliance configuration manager starts, I cannot correctly fill the fields.
Not because i'm unable to get the info, more like the controls that enable the textboxes and the rest of the control don't load correctly.
Please, help if possible.

Most of the errors shown in the console say : Refused to apply inline style because it violates the following Content Security Policy
