Squid and SSL intercept and decrypt

This post has NOT been accepted by the mailing list yet.
Messing around with squid and ssl decrypt on windows. Standard cygwin install followed the below directions.
https://advsoft.info/articles/setting_up_HTTPS_inspection_in_squid.php

I am using 3.54

below is my config. I had to move the ssl certs to the squid folder as cygwin was c:\cygwin and squid was c:\squid. I am getting proxy is refusing connections. When I remove all the ssl stuff at the bottom under #ssl de it works fine. So has something to do with that. Not sure where to go from here.

# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed

# Recommended minimum Access Permission configuration:
#

# Only allow cachemgr access from localhost
http_access allow localhost manager
http_access deny manager

# Deny requests to certain unsafe ports
http_access deny !Safe_ports

# Deny CONNECT to other than secure SSL ports
http_access deny CONNECT !SSL_ports

# We strongly recommend the following be uncommented to protect innocent
# web applications running on the proxy server who think the only
# one who can access services on "localhost" is a local user
#http_access deny to_localhost

#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#

# Example rule allowing access from your local networks.
# Adapt localnet in the ACL section to list your (internal) IP networks
# from where browsing should be allowed
http_access allow localnet
http_access allow localhost

# And finally deny all other access to this proxy
http_access deny all

# Squid normally listens to port 3128
