Nginx request port

nginxssl

I have an nginx server with SSL enabled. As it operates on a different port (than 443), sometimes it receives plain HTTP requests instead of HTTPS. I'd like to set up a redirection for that to replace the scheme automatically, I tried this code:

error_page 497 https://$host:$server_port$request_uri;

But the problem here that as the server operates in a VM and the port is forwarded to a different port, it redirects to an invalid port (from which the server got the request).

My question is: how can I parse/get the port from the request rather than the port from the server received the request?

Hopefully not too little too (eight months!) late. I had a similar question myself, to use the original request port in nginx.conf.

nginx $http_name variable

$http_name: arbitrary request header field; the last part of a variable name is the field name converted to lower case with dashes replaced by underscores

$http_host should therefore contain the request 'Host' header, if that helps.

e.g. localhost:8020

proxy_pass is able to proxy to HTTPS, this is not a problem.

You have an error in your configuration. Remove lines

ssl on;
ssl_certificate /etc/nginx/server.crt;
ssl_certificate_key /etc/nginx/server.key;
ssl_verify_client off;

These are turning on SSL server at Nginx side, which means your Nginx expects SSL connection at port 80. Since browsers send ordinary HTTP to port 80, Nginx complains "400 Bad Request The plain HTTP request was sent to HTTPS port"

Nginx with http/https – Http seemed redirected to https all the time

I don't know about the 400 error, but if you had an 301 (permanent) redirect in your previous config, the browser might still have stored this redirect in the cache and doesn't check the original. Maybe purging your caches might help.
