I receive this error anytime I try to print any base map from http://services.arcgisonline.com. If I remove the base map from my code, it prints fine. (From Firebug console:)"Error executing tool.: Layer "layer0": Unable to connect to map server at http://services.arcgisonline.com/ArcGIS/rest/services/Canvas/World_Light_Gray_Base/MapServer. Failed to execute (Export Web Map). Failed to execute (Export Web Map Task)."I get a gut-feeling it has something to do with my server's proxy, but I'm not sure. Any thoughts? Here is the proxy I'm using:
