==== BASIC INFO OF YOUR IREDMAIL SERVER ====

====

The situation is this:
I has installed IredMAil and is working perfect. (A lot of troubles with dns and ssl but thats other history).
Now I have installed in the same VM a Django Syte that is running with Gunicorn in port 8001 and is Publish in port 81 with nginx.
(I can tell cause if i do a: wget localhost:81 > I download the index of my django page)

BUUUUT!

If I try to get from another pc inside or outside the network to this webpage it always redirect me to /mail/ in port 443 and give me the iredmail page... can you help me please???

It dont matter even if I hardcode the http://cannava.com.ar > It send me to: https://cannava.com.ar/mail/

    location /archivos/ {
    }
    location /static/ {
    }

    location / {
        proxy_pass_header Server;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Scheme $scheme;
        proxy_connect_timeout 600;
        proxy_send_timeout 600;
        proxy_read_timeout 600;
        proxy_pass http://localhost:8001/;
    }
}

Important:
I put port 81 cause this VM is behind a HAPROXY that send both port 80 to 81 and 443 to 443.

Thanks for your time, hugs!
