SSL implementation on custom port for django application using nginx

Question

I am trying to host multiple django applications on the same IP. I have an django application on hosted on specific port 8001 with domain name (domain_name.com). Now on accessing https://domain_name.com, application runs pretty well, But on http://domain_name.com , another applciation hosted in port 80 loads. On accessing 'domain_name.com' how can i redirect to port 8001 for both http and https requests ?

My nginx conf for domain is as below.

server {
    listen 8001;
    server_name erostreasures.com www.erostreasures.com;
    location = /favicon.ico { access_log off; log_not_found off; }

    location / {
    include proxy_params;
    proxy_pass http://unix:/run/agmarket.sock;
}

listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/erostreasures.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/erostreasures.com/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}
