Cannot install any plugins, can I download instead (can't find download link)

Getting this message, have tried two very different hosts which suggests the problem is your end:
Your server had a problem connecting to WPMU DEV: "cURL error 28: Operation timed out after 15001 milliseconds with 0 bytes received". 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?"
