connect() failed (111: Connection refused) while connecting to upstream, client - django

Question

I am trying to deploy a django instance to ec2 . I am using a combination of nginx and gunicorn to achieve that. I got the nginx isntance and gunicorn to start correctly and I am able to get my instance running. But when i try to upload an image to the database on my application I run into this error in my gunicorn error.log :
connect-failed-111-connection-refused-while-connecting-to-upstream
Also all my api calls from the front end to the database return a 500 internal server in the console.
My nginx.conf looks like
default_type application/octet-stream;
# Load modular configuration files from the /etc/nginx/conf.d directory.
# See http://nginx.org/en/docs/ngx_core_module.html#include
# for more information.
include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
include /etc/nginx/sites-available/*;
index index.html index.htm;
server {
listen 127.0.0.1:80;
listen [::]:80 default_server;
server_name 127.0.0.1;
root /usr/share/nginx/html;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
}
# redir
And my sites-enabled/default file as
upstream app_server_djangoapp {
server 127.0.0.1:8000 fail_timeout=0;
}
server {
#EC2 instance security group must be configured to accept http connections over Port 80
listen 80;
server_name myec2isntance.com;
access_log /var/log/nginx/guni-access.log;
error_log /var/log/nginx/guni-error.log info;
keepalive_timeout 5;
# path for static files
location /static {
alias xxxxxx;
}
location /media {
alias xxxxxx;
}
location / {
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
if (!-f $request_filename) {
proxy_pass http://app_server_djangoapp;
break;
}
}
}
I tried most of the things people talked about - adding right permissisons to the folders. Changing localhost to 127.0.0.1 etc. I am relatively new to this topic so any help would be much appreciated!
Thank you

I would suggest to change default to this :
upstream app_server_djangoapp {
server 127.0.0.1:8000 max_fails=3 fail_timeout=50;
keepalive 512;
}
- remove
keepalive_timeout 5;
- why do u have two location / blocks ?
location / {
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
if (!-f $request_filename) {
proxy_pass http://app_server_djangoapp;
break;
}
}
