Nginx refuses to connect to Django container in Lightsail

I have 2 images that I am uploading to aws lightsail.

If I upload the django one it works without any issue, but trying to add to it Nginx has not been possible as Nginx cannot connect to django.

I get this error:

[30/may/2023:16:13:38] 2023/05/30 16:13:38 [error] 30#30: *71 connect() failed (111: Connection refused) while connecting to upstream, client: 172.26.45.36, server: localhost, request: "GET / HTTP/1.1", upstream: "http://172.26.18.131:8000/", host: "172.26.2.175"

this is my nginx.conf file:

server {
    listen 80;
    server_name localhost;

    location /static/ {
        root /jp/static;
    }

    location / {
        proxy_pass http://myservice.service.local:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

when I check django, it seems just fine
