Cant Log in from new Site

Hi there,

I just created a new site but I couldn't install the WPMU DEV.

It shows this error.

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 with a POST HTTP request via fsockopen or CURL?"
