IF I am using the correct IP address as shared by you ... the .162 is a Synology Web Station. How do I know that?
The reason I know that ... web page that displays right now for that
IP address says it is.
and right now it's displaying directions ...
How to publish my website ...
First line of 4 steps:
To publish your website and make it available for people on the Internet, you need to set your DiskStation to use an external IP address.
Something about EZ Internet ... etc..
So am assuming you've done that and that's why I am seeing what I am seeing .... but I should be seeing a Moodle front page - that correct?
IF so, it's an nginx web server.
Your best resource might be: http://nginx.org/en/docs/beginners_guide.html
Check nginx config to find where 'document root' is ... that's an apache term and may not be in nginx.

Where ever your 'root' is ... is where the moodle code should go.
