Deploy ASGI Daphne/WSGI Gunicorn Nginx

Problem: Error 400 when accessing application with ASGI (Daphne) and WSGI (Gunicorn) via Nginx

Guys, I’m facing problems when trying to deploy an application that uses ASGI with Daphne on port 9001 and WSGI with Gunicorn on port 8000. To forward requests, I configured Nginx to listen on port 8080. However, when trying to access the application through that port, I get error 400.

I would like to know what could be causing this error and how I can fix it. My current configuration is as follows:

ASGI (Daphne): Running on port 9001.
WSGI (Gunicorn): Running on port 8000.
Nginx: Configured to listen on port 8080 and forward requests to the Daphne and Gunicorn servers as needed.
I would appreciate any help or suggestions to resolve this issue.

The DEBUG in setting give me this text

Hi, I’m not a specialist of nginx, but can’t the problem (mentionning 2 IPs in HTTP_HOST header) be a consequence of the following being duplicated in your nginx configuration:
