Squid как https прокси не работает

Я пытаюсь запустить прокси-сервер squid

Я пытался сделать, как здесь сказано:

https://www.tecmint.com/install -squid-in-ubuntu /

, но это не работает.

Это мой squid.conf: (все остальные строки #)

# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed
acl localnet src 10.0.0.0/8 # RFC1918 possible internal network

# Deny requests to certain unsafe ports

# Deny CONNECT to other than secure SSL ports

# Only allow cachemgr access from localhost
http_access allow localhost manager

http_access deny manager


#http_access allow localnet
http_access allow localhost

# And finally deny all other access to this proxy

#http_access deny all
http_access allow all

# Squid normally listens to port 3128
http_port 3128 transparent

acl bloclsite1 dstdomain yahoo.com
acl blocksite2 dstdomain www.rediff.com
#http_access deny www.yahoo.com
#http_access deny blocksite1

acl blockkeyword1 url_regex gmail
http_access deny bad_urls
http_access allow good_url
http_access deny blockkeyword1

все сайты получают ERR_TIMED_OUT

Может кто-нибудь объяснить, почему? или, может быть, отправить ссылку на простой рабочий файл Conf?
