Nginx docker communication to php container - connection refused - docker

Question

New to docker and nginx set up at this level. Having issues getting nginx to talk to php container. Keep getting 502 Bad Gatewaywhen navigating, with the following errors from docker:
web | 2018/03/21 09:25:40 [error] 6#6: *6 connect() failed (111: Connection refused) while connecting to upstream, client: 172.18.0.1, server: web, request: "GET / HTTP/1.1", upstream: "fastcgi://172.18.0.4:9000", host: "localhost:8080"

My nginx conf:
server {
listen 80;
# listen 443 ssl;
server_name web;
charset utf-8;
client_max_body_size 10M;
root /usr/share/nginx/html/public;
index index.php index.html index.htm;
location / {
# try to serve file directly, fallback to rewrite
# see laravel docs On Nginx, the following directive in your site configuration will allow "pretty" URLs:
try_files $uri $uri/ /index.php?$query_string;
}
location ~ ^/.+\.php(/|$) {
include fastcgi_params;
fastcgi_pass php:9000;
fastcgi_param DB_HOST mariadb:33061;
fastcgi_param DB_DATABASE homestead;
fastcgi_param DEFAULT_HOME_URL $http_host;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_buffers 4 16k;
fastcgi_buffer_size 32k;
fastcgi_busy_buffers_size 32k;
}
}
and my docker compose yaml:
version: '3'
services:
web:

mariadb:

environment:

- MYSQL_PASSWORD=secret
I've attempted to rewrite the nginx .conf several times, using various guides but it will always respond with [XYZ] is not allowed here in...- which isn't overly helpful. This conf works, but just can't access the php container. Can anyone shed some light, please?
Update
I've since installed telnet on the web container and attempted to access port 9000, but its refused at command line too.
