I can't determine if whether I have a corrupt instance that needs to be recreated or if I've missed a setup step somewhere. I am able to access the REST services directory and AGS Manager pages using 'localhost' or the host/server name (ie: http://localhost/arcgis/rest or http://ip-0axxxxxx/arcgis/manager). However I am not able to access these pages with the IP address, which is how the pages are accessed when you click the links found on the Amazon EC2 welcome page. I have an elastic IP currently associated with this instance, but the same issue occurs when I'm accessing my instance without the EIP. Has anyone experienced this issue before?
