Channel.security.error only with Firefox

PeterHoffman — Fri, 25 Apr 2014 13:20:59 GMT

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:
http://gis2.suffolkcountyny.gov/gisviewer/

Any ideas?

Can you share the contents of your crossdomain.xml file?

Peter,

IE swallows a lot of error and does not allow them to come to the surface. Try setting your crossdomain.xml at https://gisservices.suffolkcountyny.gov secure attribute as true and not false, as you are using https.

Security sandbox violation: http://gis2.suffolkcountyny.gov/gisviewer/index.swf cannot load data from https://gisservices.suffolkcountyny.gov/arcgis/rest/services/BasemapTopology/MapServer?f=json.

We tried setting to true, etc w/o success.

Peter,

You did something that has fixed the issue as it now works for me in IE, FireFox and Chrome.

Very curious.

I just take care of the development side, I do not have any access to the production servers and the production server guy is out of the office, I will ask him when he gets back.

I just tried on both my PC and an externally hooked up PC w/o success.

Do you have anything different on your Firefox settings from default?

Peter,

Yesterday is was giving me the same error you reported but today when I tried it worked fine. I have no unusual settings in FF.

Here is another thing to try even though it is a JavaScript app.

JavaScript app:
http://gis2.suffolkcountyny.gov/voterinformation/

This application works OK in IE but does not display one of the map services.

Map service that does not display:
https://gisservices.suffolkcountyny.gov/arcgis/rest/services/SCVotingPrecincts/MapServer

The JavaScript app does display the map service when run from my internal test server however.
It used to work in Firefox but does not load at all now probable due to the fact that the basemap cannot load.

We have an open ticket with ESRI on these issues and we are running ArcGIS server 10.22.

Peter,

That app seems to have a proxy problem.

http://gis2.suffolkcountyny.gov/voterinformation/proxy.ashx is not working. Is this the proper URL? Did you setup your proxy configuration to allow your server?

ESRI working with our staff here found that our ArcGIS servers had a certificate problem which they are working on getting resolved.

The proxy problem may be resolved by this fix also. Other map services that are used by the app are successfully though.

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.

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.

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.
