Docker-Django-Nginx problem with http/https

Question

I'm trying to test a setup in Docker. A web server running a python application, and I want to add an Nginx service to serve it. The result I am getting is "400 bad request" error

In the Nginx container I do these tests with curl and wget, and these are the results: WGET

root@b301fc0bb378:/# wget http://web_python:8000
--2022-12-05 19:01:06--  http://web_python:8000/
Resolving web_python (web_python)... 172.23.0.3
Connecting to web_python (web_python)|172.23.0.3|:8000... connected.
HTTP request sent, awaiting response... 400 Bad Request
2022-12-05 19:01:06 ERROR 400: Bad Request.`

CURL

root@b301fc0bb378:/# curl http://web_python:8000

<!doctype html>
<html lang="en">
<head>
  <title>Bad Request (400)</title>
</head>
<body>
  <h1>Bad Request (400)</h1><p></p>
</body>
</html>

The Python container responds this: `

[05/Dec/2022 13:34:58] You're accessing the development server over HTTPS, but it only supports HTTP.

This is my nginx.conf: `

upstream web_python {
    server web_python:8000;
}

server {

    listen 80;

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Host $host;
        proxy_redirect off;
        proxy_pass http://web_python;
    }

}

`

I do not understand why the requests are confused, if my configurations are in http, it is the development phase. Thank you...

Tried it with no luck, my python container responds fine to http when I test it from browser direct to container. The problem is in that request that Nginx sends — René Sánchez, Dec 06 '22 at 02:12

The Nginx -> Python connection is HTTPS because you have

proxy_pass https://web_python;

in your nginx config.

Change it to

proxy_pass http://web_python;

to have nginx talk to python over HTTP.

Sorry, my mistake in phrasing the question. That https is because I was trying to take it to that protocol. What I currently have is: http://web_python:8000 – René Sánchez Dec 06 '22 at 02:07
