NGINX Docker reverse proxy not working on server (Works locally) - django

Question

I am running a Django app on Docker with Nginx, the configuration works perfectly locally but on the server, it doesn't.
i get the error 502 Bad Gateway in the web page
and the logs I get
2023/01/13 07:55:56 [error] 28#28: *1 connect() failed (111: Connection refused) while connecting
to upstream, client: xx.xxx.xx.xxx, server: , request: "GET /favicon.ico HTTP/1.1", upstream:
"http://xxx.xx.x.x:8000/favicon.ico", host: "xx.xxx.xxx.xxx", referrer: "http://xx.xxx.xxx.xxx/"
This is how the configuration looks
Dockerfile
FROM nginx:1.23.3-alpine
RUN rm /etc/nginx/conf.d/default.conf
COPY ./default.conf /etc/nginx/conf.d/default.conf
default.conf
upstream apii {
server api:8000;
}
server {
client_max_body_size 20M;
listen 80;
location / {
proxy_pass http://apii;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
}
# location = /favicon.ico { access_log off; log_not_found off; }
location /api {
proxy_pass http://apii;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
}
location /realestateadmin {
proxy_pass http://apii;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
}
location /staticfiles/ {
alias /app/staticfiles/;
}
location /mediafiles/ {

}
}
