Please do not alter the domians that you use?
Had this from a customer who was going to purchase a large number of licences:
"We have decided we won’t be renewing the Fusion licenses because of difficulties using it.
The product is fine and works well but it needs access to around 14 different domains which Autodesk keep updating / changing, this causes problems with our internet security settings which we are fed up with having to get our IT department to change.
We have gone back to using Inventor and a separate CNC product."
