Just started having issues where my website is unable to pull data from my API hosted on digital ocean. We use cloudflare to proxy the server but keep getting these errors:
Ngix server error logs:
2024/07/04 23:59:57 [error] 15618#15618: *7 connect() failed (111: Connection refused) while connecting to upstream, client: 172.11.111.111, server: api.website.com, request: "GET /findata/latestPrices HTTP/1.1", upstream: "http://127.0.0.1:3355/latestPrices", host: "api.website.com", referrer: "https://plex.website.com/"

IP and Website changed for privacy
Here is the current Nginx Setup:
server {
server_name api.website.com;
listen 80;
listen [::]:80;
location ^~ /values {
rewrite ^/values/(.*)$ /$1 break;
proxy_pass http://localhost:5001/;
}
location ^~ /lights {
rewrite ^/lights/(.*)$ /$1 break;
proxy_pass http://localhost:8008/;
}
location ^~ /plex {
rewrite ^/plex/(.*)$ /$1 break;
proxy_pass http://localhost:3007/;
}
location ^~ /number {
rewrite ^/number/(.*)$ /$1 break;
proxy_pass http://localhost:3009/;
}
location ^~ /findata {
rewrite ^/findata/(.*)$ /$1 break;
proxy_pass http://localhost:3355/;
}
location /ws/ {
proxy_pass http://localhost:3355/ws;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_read_timeout 86400;

Heya,
Whenever you see an connect() failed (111: Connection refused) while connecting to upstream, client: 172.11.111.111, server: api.website.com, request: "GET /findata/latestPrices HTTP/1.1", upstream: "http://127.0.0.1:3355/latestPrices", host: "api.website.com", referrer: "https://plex.website.com/"
error it almost always means that there is something wrong with your Application rahter than Nginx. As such, check your application logs and you’ll find the exact source of the problem.
Heya,
What you can do is to verify that the services (on ports 5001, 8008, 3007, 3009, and 3355) are running.
sudo netstat -tulnp | grep -E '5001|8008|3007|3009|3355'
If the services are managed by systemd, check their status:
sudo systemctl status service_name
Note: Replace service_name
with the name of the service managing your application.
Additionally, ensure the Nginx configuration for syntax errors.
sudo nginx -t
And of course check the logs of your applications running on the specified ports for any errors that might be causing them to crash or not start properly.
