[Add New Users] My server had a problem connecting to WPMU DEV: "cURL error 28: connect() tim

My name is Fernando, I am trying to install the pro version of WPMU DEV” in my WordPress sidebar. I am following the steps but when I try to conect I get this message.
"Your server had a problem connecting to WPMU DEV: "cURL error 28: connect() timed out!". 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/v2/ with a POST HTTP request via fsockopen or CURL?"
Thanks
