I am attempting to use Cloud Builder to create an ArcGIS Server site on Amazon EC2. Upon applying all of the settings and clicking "Finish" to create the site, it is crashing and popping up an Execution Error (screenshot attached). I have verified the proper AMIs for Esri ArcGIS Enterprise 10.5.1 with SQL Server Express (May 2018). I am using Windows 10. If anyone has some input or seggestions, I would be much appreciative.
