The server connection got disconnected between sending Squid the reply
headers and the message payload they were attached to.

If you have a Squid between 3.2.0 and 3.5.5 (inclusive) please upgrade.
Which is processing SSL-bump, NTLM or Negotiate auth (even just relaying
those in www-auth form). It is probably bug 3329 related.

If you have a more current Squid "debug_options 11,2" should show you
the HTTP headers going through to eyeball if they had any kind of fatal
syntax problem that would make Squid abandon the connection.

Otherwise it would seem to be the server disconnecting. There can be a
lot of reasons for that.
