Setting up EMQX behing nginx reverse proxy

Question

I'm trying to setup emqx mqtt broker behind an nginx reverse proxy, unfortunately without success.

I'm using the following configuration.

nginx.conf

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}


stream {
  upstream stream_backend {
     server  127.0.0.1:1883 weight=1;
  }

  server {
      listen 8080;
      #proxy_send_timeout 2h;
      #proxy_read_timeout 2h;
      proxy_connect_timeout 150s;
      proxy_timeout 150s;
      proxy_pass stream_backend;
      proxy_buffer_size 3M;
      tcp_nodelay on;
      #proxy_protocol on;
  }
}

emqx.conf

node {
  name = "[email protected]"
  cookie = "mysecret"
  data_dir = "data"
}

listeners.tcp.default {
  bind = "127.0.0.1:1883"
  proxy_protocol = true
  proxy_protocol_timeout = 30
  enable_authn = false
}


dashboard {
    listeners.http {
        bind = 18083
    }
}

nginx and emqx are running within the same docker compose file.

Trying to connect is giving the following error

emqx | 2023-09-26T23:20:47.213039+00:00 [error] supervisor: 'esockd_connection_sup - <0.2858.0>', errorContext: connection_shutdown, reason: {invalid_proxy_info,<<"GET /mqtt HTTP/1.1\r\n">>}, offender: [{pid,<0.3309.0>},{name,connection},{mfargs,{emqx_connection,start_link,[#{enable_authn => false,limiter => undefined,listener => {tcp,default},zone => default}]}}]

Update

Updating the emqx.conf to run native mqtt solved the mqtt connection problem

node {
  name = "[email protected]"
  cookie = "mysecret"
  data_dir = "data"
}

listeners.tcp.default {
  bind = "127.0.0.1:1883"
}


dashboard {
    listeners.http {
        bind = 18083
    }
}
