We have deployed a 10.6 Enterprise instance on Amazon Webservices
Installed a License Server configured the Pro Licenses for Portal assigned licenses etc...
When we use ArcGIS Pro on the Amazon Instance it works
However if we try and use the Pro License off the AWS we can't connect, it times out.
However we can add that portal and publish to it. (but we cant use that Pro License)
How have users got around this?
