Forward Proxy Server with Nginx ngx_http_proxy_connect_module

Official docs https://github.com/chobits/ngx_http_proxy_connect_module says:

server {
     listen                         3128;

     # dns resolver used by forward proxying
     resolver                       8.8.8.8;

     # forward proxy for CONNECT request
     proxy_connect;
     proxy_connect_allow            443 563;
     proxy_connect_connect_timeout  10s;
     proxy_connect_read_timeout     10s;
     proxy_connect_send_timeout     10s;

     # forward proxy for non-CONNECT request
     location / {
         proxy_pass http://$host;
         proxy_set_header Host $host;
     }
 }

,but if your remote server is running on non-standard http port e.g. 8080

Just update proxy_pass to http://$http_host;

server {
     listen                         3128;

     # dns resolver used by forward proxying
     resolver                       8.8.8.8;

     # forward proxy for CONNECT request
     proxy_connect;
     proxy_connect_allow            443 8080;
     proxy_connect_connect_timeout  10s;
     proxy_connect_read_timeout     10s;
     proxy_connect_send_timeout     10s;

     # forward proxy for non-CONNECT request
     location / {
         proxy_pass http://$http_host;
         proxy_set_header Host $host;
     }
 }

Done
