Encountered this gem of an error message:
SSL error 4: The Operation Completed Successfully
The error pops up when you try to start an application from the Citrix Receiver for Web, after login.
Found this article from Citrix that discusses a know bug with the new Citrix Receiver 4.7, but in our case this shouldn’t be the issue as we are using a VPX and not MPX or SDX.
After some thorough testing, I concluded that Citrix Receiver 4.7 was indeed the problem, and the fix is to either downgrade to 4.6 or upgrade Citrix Netscaler to the recommended version. We decided to upgrade Netscaler to the latest stable version of 11.
