Nginx Default: Why is location / not forwarded to reverse proxy? - wordpress

Question

I want NGINX to forward any requests to the domain name http://home.com to proxy_pass http://localhost:8866;. I have set a root root /home/owncloud;, in the NGINX configuration file where the document root of ownCloud is located. This should point to http://home.com/owncloud Under the http://localhost:8866 I have a Docker container running hosting Wordpress. However, NGINX always points the Reverse Proxy to the actual document root of the server (root /home/owncloud) when I try to access http://home.com
Thank you for your input on this - I already browsed through a lot of documentation, but currently I am not able to find a solution myself. Thanks!
This is my NGINX configuration file:
upstream php-handler {
server unix:/var/run/php5-fpm.sock;
}
server {
listen 80;
server_name home.com;
index index.html index.htm index.php;
# enforce https
return 301 https://$server_name$request_uri;
}
server {
ssl on;
listen 443 ssl;
server_name home.com;
server_name 123.456.789.10 ssl;
ssl_certificate /home/ssl/certificate.pem;
ssl_certificate_key /home/ssl/owncloud.key;

If you need to forward all requests another port at your localhost, you need merely this:
location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_pass http://localhost:8866$request_uri;
proxy_read_timeout 90;
}
Note, there is no "=" equal sign before the slash /. location / {} means "exact match of /".
In your code nothing really tryes to forward all requests to localhost. Only requests to index page (document root, i.e. "/") are forwarded.
If you pass all requests to the the process at localhost:8866, none of other location sections will even be tested, so once you make sure your proxy_pass works, you may delete them.
