Just an idea - I just had two users in a row complaining for much the
same reason. Turned out they both tried to access a secure page and
had entered my Squid as HTTP proxy, but not as Security proxy, in their
browser setup. So all went well as long as they did only regular HTTP
accesses, but for SHTTP the browser would try to connect directly, and
fail with a DNS error. (My users cannot make direct outside connections,
only through the proxy, and DNS isn't available to them.)
