API on AWS - Additional Web Server

Hello,

My support ticket said API issues are not supported and you have to post on THWACK.

When I attempt to use REST API to my SolarWinds Additional Web servers I get an error connecting.  When I connect directly to the MPE it works as expected.

Are the AWS not a support configuration?  Is there something additional that needs to be done or configured to use the AWS? 

Edit: Error code: PR_END_OF_FILE_ERROR

2nd Edit: when I go directly to the web server I get a 404 to the API address (:17778/SolarWinds/InformationService/v3/Json/Query, or /API)
