I may be facing a unique issue. My ArcGIS server is running within my company network.The server has picked up the proxy settings of the box it is running in.
But to serve the printing request, the server bypasses this proxy settings and calls url(services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer) directly. As a result this request is getting blocked at the company firewalls and the request is failing. When the firewall was disabled the printing is a success.
I have followed this link http://resources.arcgis.com/en/help/main/10.1/index.html#//015400000309000000
How do I route all the server requests to the Internet through my proxy server?
I am running ArcGIS 10.1 Server on Windows.
