[squid-users] Squid 3.1.0.17<--> Google/YouTube "(101) Network is unreachable",, error???

Hi,

Squid has always been working fine. All websites, except Google, still
work fine! As far as i know nothing changed on my part, except the
weekly Fedora updates.

My internal users get this "(101) Network is unreachable" error message
when they go through the proxy. My iptables allows ALL outgoing
connections.
When they hit "Reload" or ^R the page loads fine. But after a while when
they go to google again they get the same error. Hit ^R and it works again.
When bypassing the proxy, the connection also works fine!

Only with Google! Other websites work fine!

When i jump to the squid server and issue a wget to
http://www.google.com with and without the proxy i get following results:
