[squid-users] New squid build https not working

[Ryan Slick]

Hi Guys,
We built a new squid server on windows, the config as far as I can see is basically the same as our existing proxy (which works fine)
but the problem is http will work fine, https does not.
the client browser sees the error: "err_tunnel_connection_failed" when trying to load any page with https
and the squid logs show:https10.50.100.12 - - [15/Feb/2016:09:10:04 +1100] "CONNECT yahoo.com:443 HTTP/1.1" 0 932 TCP_MISS:DEFAULT_PARENT10.50.100.12 - - [15/Feb/2016:09:10:05 +1100] "CONNECT www.yahoo.com:443 HTTP/1.1" 0 948 TCP_MISS:DEFAULT_PARENT10.50.100.12 - - [15/Feb/2016:09:10:05 +1100] "CONNECT au.yahoo.com:443 HTTP/1.1" 0 944 TCP_MISS:DEFAULT_PARENT
http10.50.100.12 - domain\username [15/Feb/2016:09:15:14 +1100] "GET http://www.simpleweb.org/ HTTP/1.1" 200 8345TCP_MISS:DEFAULT_PARENT

The obvious issue seems to be the missing username in the https request. Is there anywhere I can start looking for the issue?
Thanks
