I can not login WPMU DEV Dashboard

Hi! I'm koji.Japanese.
I installed your Dashboard,and fill with login info.But I had this error.
"php on my server properly configured to be able to contact https://premium.wpmudev.org/wdp-un.php with a GET HTTP request via fsockopen or CURL?"

So I heard my admin,then he answerd "Yes our server' cURL is active."

This is my server's phpinfo()

http://webtan-tsushin.com/Connections/jyouhou.php

cURL support is surely enabled.
What should I do next?
