Basically title is pretty simple, yet my problem is kinda bigger.

First of all, few words about my current setup.
I got domain on OVH, lets say EXAMPLE.com. I use personalized DNS Servers pointing as follows:
ns1.EXAMPLE.COM and ns2.EXAMPLE.COM to IP Address of my VPS.

on my VPS there is bind9 server with kinda properly configured dns server (i believe so).

Created a domain with DNS Support: EXAMPLE.COM and it auto-created a directory: "/home/admin/web/EXAMPLE.COM/public_html/".
Whenever i go into my domain address - EXAMPLE.COM, i see properly contents of /public_html/
Now the trickier part.

Im creating the subdomain, lets say: TEST.EXAMPLE.COM, and similar from the example above, it creates the directory "/home/admin/web/TEST.EXAMPLE.COM/public_html/".
However 2 things that bothers me here:

1. When i use "http://test.example.com" in web browser, it returns me an error: "This webpage is unavailable. Ip couldnt be find, blah blah check ur dns servers etc."
2. When i use "http://www.test.example.com" in web browser, it actually shows me the site, however it shows the site from directory: "/home/admin/web/EXAMPLE.COM/public_html/".

It created the subdomain folder in /home/admin/web/, however its not using this directory, but the one for domain EXAMPLE.COM.

So basically 2 questions. What do i need to change to make my subdomains work WITHOUT "WWW" + Why it shows site from main domain, instead of subdomain.

Thanks in advance. Kinda bothering a lot with it.
(Still a bit newbie in all that dns'y stuff, yet in 2nd post will provide screenshots of my current configuration)

Aint sure if there is anything else needed for configuration, so if anything comes to ur mind, ill provide more data.

I wish i said "found solution", but apparently, it just started working. Was trying a bit more with DNS Records, adding weird stuff like "@ A 123.123.123.123", removed website, added again, and it works. No idea what fixed my issue, but prefer not risking bricking it again.

Aaaand it stopped working again. I gont get it at all xD
