Django-axes seems to ignore ipware settings behind Nginx

I'm struggling to set up my django-axes behind Nginx reverse proxy to take the HTTP_X_FORWARDED_FOR instead REMOTE_ADDR. I've tried all three variations as outlined here: https://django-axes.readthedocs.io/en/latest/4_configuration.html. I've tried setting the ipware fields in isolation as well as in combinations. Left-most and right-most also didn't make any difference., ip_address from Axes' attempts was always populated with REMOTE_ADDR.

I'm 100% sure that request.META contains both HTTP_X_FORWARDED_FOR as well as REMOTE_ADDR. I checked this by inserting a debugging middleware in front of axes. My logs show that both values are valid and I can manipulate the IP logged by Axes by modifying REMOTE_ADDR in my middleware:

class OverwriteRemoteAddrMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        logger = logging.getLogger('django.request')
        xff = request.META.get('HTTP_X_FORWARDED_FOR')
        logger.info(f"[Middleware] Before: HTTP_X_FORWARDED_FOR={xff}, REMOTE_ADDR={request.META.get('REMOTE_ADDR')}")
        # Set REMOTE_ADDR to a fixed unrelated value for testing
        request.META['REMOTE_ADDR'] = None
        logger.info(f"[Middleware] After: REMOTE_ADDR={request.META['REMOTE_ADDR']}, X-Forwarded-For={xff}")
        return self.get_response(request)

This is my full settings.py that I'm currently using in a minimal django test project:
