Why are some users getting rsl error in flash app?

Question

When some of my users try to access my flash application, they receive an error

RSL Error 1 of 1

That is it, there is no error code or anything. This page works for them in Internet Explorer, but they primarily use Chrome. It also works fine for me and another coworker in Chrome. We are on the same network.

Here is my .actionScriptProperties file

EDIT: Ok, the user didn't send me the full page, which contained an error number The full error is:

RSL Error 1 of 1
Error #2048

EDIT2: Crossdomain.xml (located at https://example.com/crossdomain.xml)

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

EDIT 3: I took a look at the developer network information. It seems like on my machine it is not even trying to request the crossdomain file, while on my coworker's machine, it is requesting it on http and https.

Here is the code that embeds the flash:

  </object>

EDIT 4: Also, when the crossdomain is called from my coworkers computer it is called using our other domain

https://www.example2.com/crossdomain.xml
http://www.example2.com/crossdomain.xml

Whereas the request for the original page is

https://example.com/cfa/canvastransfer

The thing is these all need to work on all 3 of our domains the same.

EDIT 5: Updated allowScriptAccess to be always, instead of sameDomain on the code that embeds the flash. No change.

EDIT 6: In one of my mxml files, I am calling this (still having same issues):

Security.loadPolicyFile("https://example.com/crossdomain.xml");

Answer 1

Do you have a crossdomain.xml file deployed on the server that serves the rsls?

This might also be caused by trying to load an rsl via http when your app swf is served via https.
