Has anyone gotten url_for in a Jinja2 template to return an HTTPS url when using nginx and gunicorn?

Hi, there are several similar questions out there, but I haven't found one that covers gunicorn and nginx specifically.

I'm having the same problem as others, where the url_for function in a Jinja2 template is returning an HTTP URL, but my production website uses HTTPS, so the content is blocked by most browsers for being potentially insecure.

As I understand it, the solution is to add --forwarded-allow-ips to the gunicorn arguments to allow us to use the forwarded HTTPS scheme for any IP address:

Snippet of my nginx setup:

location @yourapplication {
gzip            on;
gzip_buffers    8 256k;

proxy_pass http://127.0.0.1:8000;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Protocol $scheme;
}

Snippet of my gunicorn unit:
[Service] ExecStart=/apps/venv/bin/gunicorn -b 127.0.0.1:8000 -w 2 -k uvicorn.workers.UvicornWorker app:app ... --forwarded-allow-ips * --user appuser

This is not working for me, however. I'm still getting url_for returning HTTP URLs. I thought the FastAPI/Jinja2/nginx/gunicorn stack was fairly common, so I'm just looking for confirmation that someone has achieved what I am trying to do. If you are using this stack and have successfully gotten an HTTPS scheme out of url_for, can you let me know what you did?

Ope, I'm guessing the reason there are not any specific questions about this stack are because I made it more complicated than it needed to be. I don't even need to use url_for in my Jinja2 template; I can just hardcode the path to the static directory with a slash in front of it, like <script src="/static/js/compiled_js/my_js.js"></script>. I'm still not sure how to get url_for to work, but I'm going to close this because it's not necessary for my use case.
