I'm using Cloud Builder to create an ArcGIS for Server 10.4 site on Amazon Web Services (AWS). I'm pretty much choosing the defaults (Windows, no geodatabase, mxlarge instance) and get all the way through to the end of the process. Cloud Builder says it is creating the site. It gets as far as creating the Load Balancer in AWS but can't create the instance. Here's the error I get:
ERROR 2016-03-16 02:07:09 Failed to create site 'ArcGISServerWindowsCB'. In order to use this AWS Marketplace product you need to accept terms and subscribe. To do so please visit http://aws.amazon.com/marketplace/pp?sku=3e6mr1zhg21t3385p1jiom88d (Service: AmazonEC2; Status Code: 401; Error Code: OptInRequired; Request ID: 55524436-926b-41f5-baf2-773067188242)
The URL in the above error message just takes me to the ArcGIS Server AMIs page. I could go down this route but this is what Cloud Builder helps the user avoid doing.
I successfully created an ArcGIS Server site on Ubuntu last month using Cloud Builder with no problems. Any ideas?
