Layer Load Error Channel.Security.Error

[BillBean]

I'm getting an error when I'm trying to use REST services from Server A1 to Server B2

[ATTACH]6733[/ATTACH]

I'm using a crossdomain.xml
setup like this

<?xml version="1.0" encoding="UTF-8"?>
<cross-domain-policy>
 <allow-access-from domain="*"/>
 <site-control permitted-cross-domain-policies="all"/>
 <allow-http-request-headers-from domain="*" headers="*"/>
</cross-domain-policy>

Some post say this is a local firewall issue with the server I'm using.  Other report it's an issue with the crossdomain.xml file???

Any ideals..

Thank you for the input..

Still getting the error...I don't believe it's a crossdomain.xml ... I've tried multiple configurations....

Can you have your IT dept. monitor the firewall to see if anything gets logged?

Your cross domain looks to be the same as the one I use on our public server except I don't have
encoding="UTF-8"
