Trying to reverse proxy to API URL not working

Hi all,

I’m trying to create a reverse proxy for my API url and it is not working. The API is working if I use curl localhost:8800. It is on port 8800. My reverse proxy config is as follow:

server {
    listen 80;
    listen [::]:80;

    location /api {
        proxy_pass http://localhost:8800;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_cache_bypass $http_upgrade;
    }
}

I just keep getting 404 error with this. Please help. Thanks.

Hi there @knpaing,

Your Nginx Server Block looks correct, as far as I can see it is configured so that it would work if you visit your_droplet_ip/api. What happens if you run:

curl your_droplet_ip/api

If you are still getting a 404 error, I could suggest checking your Nginx access and error logs:

  • tail -100 /var/log/nginx/error.log
  • tail -100 /var/log/nginx/access.log

And also making sure that you’ve restarted Nginx so that the reverse proxy rules have been loaded.

Hope that this helps!
Regards,
Bobby
