@thelettuce, thanks for the pointer. I had already made that change to get it working.
@hitendra-chopda I was hoping that the next release would have incorporated a configurable option approach to the solution rather than me having to modify the code every time a new version was released.

added some debug code in your class-mdbp-rest-api.php file and it has revealed the issue.

WP_Error Object
(
    [errors] => Array
        (
            [http_request_failed] => Array
                (
                    [0] => cURL error 60: SSL certificate problem: unable to get local issuer certificate
                )

        )

    [error_data] => Array
        (
        )

)
