Could not do a request to UsabilityDynamics.com while activating add on

When receiving an error: “There was an error making activation request. Could not do a request to UsabilityDynamics.com” when trying to activate a plug-in, please contact your host provider and ask them to let the requests be done for UsabilityDynamics site. They should support SSL V3.

If server does not have support for SSL V3, evident via this error:

:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure

then the workaround is to override the API URL like so to your wp-config.php file:

Put this code somewhere in the beginning, before the code that includes wp-settings.php, which is usually at the bottom.

if( !defined( 'UD_API_URL' ) ) { define( 'UD_API_URL', 'http://api.usabilitydynamics.com/' );}

That should fix the issue by making the requests NOT use https.
