I'm getting this error when trying to use AWS Elastic Beanstalk to connect to my Django code:

[error] 2540#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 172.31.23.63, server: , request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8000/", host: "172.31.14.130"

My log is displayed below:

Previously, I also received an error where it said

Dec 21 04:14:38 ip-172-31-14-130 web: Invalid HTTP_HOST header: '172.31.14.130'. You may need to add '172.31.14.130' to ALLOWED_HOSTS.
Dec 21 04:14:38 ip-172-31-14-130 web: Bad Request: /

I did add 172.31.14.130 to the ALLOWED_HOSTS section of my settings.py file and then received the /var/log/nginx/error.log and when I try to access my webpage, it tells me the site took too long to respond - any help/suggestions would be greatly appreciated!

You should use express to listen 8000 port since its try to listen http://127.0.0.1:8000/

const port = process.env.port || 8000;
app.listen(port, ()=>{console.log(`listening on port ${port}....`)})

You can also set the port in AWS EB environment variable under configuration -> system -> Environment properties. Example below.
