Can't access crossdomain.xml - web player

Hi,
I’m having a little issue with crossdomain file. When I create the game in our local server it worked fine. But we exported all the project to the client server and it still working fine for all external connections. The problem is that the client can’t play it from their own servers. The problem is that web player can’t access to crossdomain. I’m not sure what is the problem, crossdomain configuration, .htaccess or any other network configuration.
What can I do? Help!

The crossdomain file:

<cross-domain-policy>
       <allow-access-from domain="*"/>
</cross-domain-policy>

Usually the crossdomain file needs to be placed within the root folder of your web app on your web server (or client’s in this case). If you do not know the exact root, try to use the browser dev tools on the network requests to determine the full url where the browser is looking for it so you can place the file where it’s requested. Also you can try to get a sniffer like Fiddler to now more details about where is the crossdomain.xml required to be located. Once it is located in there, you can check if the browser can access the file by typing the file url in the browser, something like

http://clientserver/mygameapp/crossdomain.xml

If there is a permission issue, the web server would let you know on that request.

Here’s the link for Fiddler in case you need the sniffer.
