Reverse proxy from nginx to squid

nginx proxy reverse-proxy squid http-proxy

in nginx:

proxy_pass http://@squid;

in squid:

http_port 3128 vhost

and that's all you need for fix this https://imgur.com/qtgrZI9 error

nginx proxy reverse-proxy squid http-proxy

I had this same problem, solved it by setting squid to run in transparent mode, like this:

http_port 3128 transparent
