Channel.security.error only with Firefox

[PeterHoffman]

We have a flex app that works fine using IE but get the security error implying crossdomain.xml problems using Firefox.

Here is our public site:

Any ideas?

Peter,

   I would not expect to see the error I was seeing when accessing the proxy page if there was not an issue with the proxy though.

Hi Robert,

If I may, I would like to share my similar experience with Firefox.  I did not have any issue with Chrome and IE but I had same error on my ArcGIS Viewer for Flex apps. ( Silverlight is okay).

After several solutions I tried, I found out that simply adding an entry in the Connection Settings - > No Proxy for: in my case my local ArcGIS Servers ( without the http://) , the Flex Web works.   This is not required for Chrome and IE.

Reginaldo,

   Thanks for the info. I will try and remember this when helping others.

UPDATE:

Our network/server/security guru applied the fix for this particular issue:

The issue stems for Firefox adhering to strict interpretation of the SSL certificate chain. The appropriate intermediate ???link??? between the THAWTE root Certification Authority and its Intermediate Certification Authority was not made inside the CITRIX Netscaler. Once the appropriate certificate was loaded and linked the issue was solved.
