Hi,
I am trying to setup squid3 as an HTTPS proxy using the tutorial given
[here][1]. I have properly setup the proxy settings in my browser and when I
try to hit **HTTP** web sites, I am able to connect successfully. However, I
keep getting a "Connection timed out error" whenever I hit an **HTTPS**
protocol web site and the following error in my `/var/log/squid3/cache.log`:
2016/06/20 19:12:47| NF getsockopt(SO_ORIGINAL_DST) failed on
local=<local_ip_address>:3129 remote=<remote_ip_address>:55209 FD 8 flags=33:
(92) Protocol not available
Here is my /etc/squid3/squid.conf file (commented lines removed for brevity):

I have spent a lot of time googling this error but could not arrive at a
solution which would configure squid as an HTTP proxy. How do I get this
working?
