I have just installed Squid proxy server on a CentOS 7 system and everything went smooth but the proxy loads only the Google sites like YouTube, Google Search, and so on...
when I visit another site it shows "ERR_CONNECTION_RESET" on my browser.
My squid.conf file is the basic one but I commented all the "http_access" lines and kept only "http_access allow all"
Also I commented "cache_dir" and added "cache deny all" because I want Squid to run as a proxy only without caching.
Also I have set "dns_v4_first on" and "dns_nameservers 184.108.40.206 220.127.116.11"
Please note that HTTP sites work fine but not HTTPS (except Google sites)
I dont know what is causing the issue but I know that only HTTP work especially that the browser resolves the HTTPS sites and it redirects from http:/ to https:// but then it shows "ERR_CONNECTION_RESET"
Note that I have Squid 3.5
Edit: The access.log file shows "TCP_MISS" on the non-working sites
