[Python] Infinite redirection loop for Django backend (hosted on railway) application (hosted...

tl;dr I'm getting an infinite loop when I request my django backend, and I don't know how to fix it

I'll give some context to what's happening:

• My django backend works on localhost (I used nginx as a reverse proxy when developing it)
• I've got a cloudfare domain, and I've registered by backend to it on railway
• when I try to connect to the backend over the Cloudflare domain, I keep getting redirected to the page I requested- so it's an infinite loop
• I'll give some outputs to show what's happening

Request headers:

And the response:

This request and response keep happening until the browser steps in.

If I curl the endpoint, I just get:

<a href="my backend domain">Moved Permanently</a>.


So Cloudflare has the flexible SSL/TLS encryption mode, and in my settings.py, I have:

SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')
SECURE_SSL_REDIRECT = False


I've tried removing/toggling these settings in settings.py, but to no avail. Changing the SSL/TLS mode to full or full (strict) in Cloudflare also doesn't fix the issue (full strict causes a bad gateway).

So my question is: what do I need to have in my settings.py and/or Cloudfare to prevent this infinite loop? Where in my backend code should I check to fix this?

Please do request more information if needed.
