Authorization Failure
Nothing would authorize! I started with the templates and have since terminated that AMI, started over with a blank box, ensured the proper ports were open, and use cloud builder to deploy. Much easier. Note that these do not come bundled in the cloud templates. All the templates include are the self signed certs with Portal/ArcGIS Server.
We also lost access to all our licenses after changing the machine instance and licenses becoming "untrusted." No help from ESRI, as it's a "known issue" basically lost a week of trying to fix this, to no avail.
Not easy to configure and the official documentation is very poor.
