dashboard not integrating with my WP website

I am getting following error while trying to login to WPMU DEV Dashboard from my WP dashboard. Can you please guide me how to resolve it.

Your server had a problem connecting to WPMU DEV: "cURL error 7: ". Please try again.

If this problem continues, please contact your host with this error message and ask:

"Is php on my server properly configured to be able to contact https://premium.wpmudev.org/api/dashboard/v1/ with a POST HTTP request via fsockopen or CURL?"

Thanks in advance.
