Pages loading after the second attempt

[friskee]

I have recently setup up squid and dansguardian onto a spare server. When using the proxy if somebody tries to go to any site, for example https://www.google.com.au they get a page saying:

_This page can't be displayed

•Make sure the web address https://www.google.com.au is correct.
•Look for the page with your search engine.
•Refresh the page in a few minutes.
•Make sure TLS and SSL protocols are enabled. Go to Tools > Internet Options > Advanced > Settings > Security
Fix connection problems_

But if they try to go again 2 seconds later the pages loads fine.

Same problem here, with pfsense 2.1, squid3 and dansguardian…
