Question
connect() failed (111: Connection refused) while connecting to upstream
Hi all,
Followed this tutorial to get Let’s Encrypt working on my Nest.js/Node server.
Everything works - running sudo nginx -t
returns:
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
However, accessing my domain gives me a 502 Bad Gateway error. Specifically (from /var/log/nginx
):
15004#15004: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 77.98.141.183, server: ww2.zone, request: "GET / HTTP/2.0", upstream: "http://127.0.0.1:8000/", host: "ww2.zone"
Here is my /etc/nginx/sites-available
file:
Default server configuration
server {
listen 80;
listen 127.0.01;
listen [::]:80 default_server ipv6only=on;
return 301 https://$host$request_uri;
}
server {
# Enable HTTP/2
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name ww2.zone;
# Use the Let’s Encrypt certificates
ssl_certificate /etc/letsencrypt/live/ww2.zone/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/ww2.zone/privkey.pem;
# Include the SSL configuration from cipherli.st
include snippets/ssl-params.conf;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://localhost:8000/;
proxy_ssl_session_reuse off;
proxy_set_header Host $http_host;
proxy_cache_bypass $http_upgrade;
proxy_redirect off;
}
}
And my server is within a git Repo within home/username
.
The code to listen on the port is:
await app.listen(process.env.PORT || 5000);
This used to be process.env.PORT || 80
but that would throw:
Error: listen EADDRINUSE: address already in use :::80
Any ideas? Pulling my hair out atm.

Hi Bobby,
One more to the list having this issue.
nginx.conf
Node.js server is running correctly on PORT 4000 because I can to a POST to it, get a response and see data in my MySQL
