vRealize Orchestrator Secure Connection Failed

If we are working with vRealize Automation and using the integrated vRealize Orchestrator. And after starting the vRealize Orchestrator Configurator service, if you receive an error while connecting to vRealize Orchestrator configurator Page (https://vCAC.vmfootprints.Org:8283/vco-config), Secure Connection Failed. An error occurred during a connection to vCAC.vmfootprints.org:8283. SSL received a weak ephemeral Diffie-Hellman Key in Server Key Exchange handshake message.

This is because that the webserver we are trying to reach is vulnerable to recently published logjam vulnerability: http://arstechnica.com/security/2015/05/https-crippling-attack-threatens-tens-of-thousands-of-web-and-mail-servers/ please report that to webmaster of the site in question to fix that issue...

But if you want to ignore it and want to continue here is a workaround for Firefox 39 and above:

1.       Open a new tab in Firefox and enter “about:config” in the URL field and press enter

2.      Accept the “I’ll be careful, I promise!”

3.      In the search field at the top, enter "security.ssl3.dhe_rsa_aes"

4.      Double click each result (128 and 256) to toggle the Value to "false"

Now retry your site - it should work now. Remember to change these settings back when you're done.
