Error while using HTTPS security, URL =

I've created a web map which is using ArcGIS 10.1 Server ExportWebMap service.
This is installed on the DMZ server in the corporate network.
Our network team applied a firewall rule change for outgoing internet connection from this DMZ server to via port 443.

I get the following error msg when I clicked the Print button on my web map on Chrome:
  "message":"Unable to complete operation.",
   "Error executing tool.:
   Layer \"layer0\": Unable to connect to map server at\n
   Layer \"layer1\": Unable to connect to map server at\n
   Failed to execute (ExportWebMap).\n
   Failed to execute (Export Web Map)."

When I tested the connection "" on IE on the DMZ server and I was able to see its responses for this end point.

Thus I looked at the Logs on the ArcGIS Manager, the first error logged by this request was -
"Error while using HTTPS security, URL =, HTTP Status code = 0 and Status Text = "
But again, I could its responses on IE on the DMZ server.

Is this because of the Proxy settings?
The following is my proxy.config :
<?xml version="1.0" encoding="utf-8" ?>
<ProxyConfig mustMatch="true">
    <serverUrl url=""
    <serverUrl url="https://myServer/arcgis/rest/services/"

This web map service is pretty much ready for delivering to our clients except this issue.
Do you guys have any ideas???

Thanks in advance.
