Print Widget Error-Flex 3.0 RPC Fault faultString="Security error accessing url"

[JayDira]

Hello,

I am having an issue with the print widget.
When I run the print widget with Flex 3.0 within the host server it works perfectly.
But, when I go to my desktop and run my Flexviewer 3.0 map> then open the Print Widget.
I get the below error...

Error executing print task:

[RPC Fault faultString="Security error accessing url" faultCode="Channel.Security.Error" faultDetail="Destination: DefaultHTTP"]

What can be the cause?
Thanks

Try to put crossdoamin on host, eg: If IIS put crossdoamin.xml on wwwroot directory

crossdomain.xml:

<?xml version="1.0" ?> 
<cross-domain-policy>
 <allow-access-from domain="*" secure="false"/>
 <site-control permitted-cross-domain-policies="all"/>
 <allow-http-request-headers-from domain="*" headers="*"/>
</cross-domain-policy>
