I assume, because you mention your DNS server, that both your clients (which
can access the website) and the squid proxy (which cannot) are pointing to
this for their primary name resolution. Is this assumption correct?

Does your DNS server run 'split DNS', providing different answers depending
on the IP address of the questioner? If so, do your clients and your proxy
fall into different ranges as far as the DNS server is concerned?

Do you have any NAT involved here?

Just one final question: can the squid machine proxy correctly for other
websites - ie is the problem just associated with your own web server?
