I am using arcgis 10.1 and wanting to publish some test data to my trial ArcGis Online account and having trouble. It says Proxy server got bad address. I am using the address that is visible when i am in my trial version online account website. http://aeroatlastest.maps.arcgis.com:8080/rest/services. I also tried http://aeroatlastest.maps.arcgis.com:6080/services. What am i doing wrong?
