what I’d like to achieve is the following:

client -> nginx proxy -> db server -> give response to client

This is what my nginx config looks like:

    server_name {site}.dev www.{site}.dev;

    location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            try_files $uri $uri/ =404;
    }

    location /api {
            proxy_pass http://localhost:3000/api;
            # proxy_set_header Host $host;
    }

For more context, from http://localhost:3000/api I am making a call to an express server on the database server that then makes the database request.

Now, I’m seeing on both nginxserver:3000 and dbserver:3000 that the requests are being received, yet I get a 502 bad gateway response on the client.

I’d like to be able to get the response from the database server on the client.

I’d appreciate any help, thank you !
