Error when opening admin.php

Hello all,

I haven't logged into to CMS Builder in some time, and am now getting an error when I try to pull up the admin.php page. The error is:

getPage: Error opening socket: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. (10060)

The server it's hosted on is our own, so I know there hasn't been any upgrades to the server. Does anyone know what may be causing this? There are similar errors in posts, but no solutions were published.

Thanks, Erin
