Sub domain Not working in ISPConfig 3

Hi,
I am new to ISPConfig. Setup a server two weeks ago and bought manual last week, I manged to setup two servers after a few attempts a primary server and secondary DNS server only. I have tested most of all the the settings and everything works really well except sub domains for websites, I have battled for the past two days :

I setup website and DNS and go to example.com it works.
I log in to ftp for example.com and create folder def and in folder I create index.html and go to example.com/def and it works
I go to DNS and make A record def i go to subdomain and create def.example.com Flag L and set Path /def/ then go to def.example.com does not work. I have even Redirect to google.com but also does not work.

ANY HELP ?

 

Have you created a website for def.example.com?

 

No cause it is a folder in my main site that needs to be accessed by the main site. Is it optimal ? cause if you look at this video, this is what i am trying to do but not working for me ?

 

In there, subdomain for website is created (2:40 onwards), that is what @Taleman trying to say, so did you do that?

 

I created example.com as web site and def.example.com as sub domain and made A DNS Record for def.example.com

I did not create def.example.com as website because how would example.com access def.example.com. def.example.com is sub domain like example.com/def/ then main site can access the folder and if go to def.example.com it loads content of example.com/def/ but when i create it it does not work when i load def.example.com it gives error

This site can’t be reached
def.*********.com’s server IP address could not be found.

• Go to **************. com
• Search Google for def **********

ERR_NAME_NOT_RESOLVED

 

The A Record is there do you also need a CNAME ? When i add the CNAME ISPConfig tells me duplicate A Record or CNAME

 

Where is the log for ISPConfig DNS adding and editing ? on ISPconfig the A record is there but when i do i dig

dig +nocmd yourdomain.com any +multiline +noall +answer

None of the A records are displaying FTP,MAIL ect...

 

In /ect/bind/pri.example.com.err the right DNS settings are there but In /ect/bind/pri.example.com there are only default setting doing a dig on domain i only get mail.example.com as additional A Record after using mail.example.com to sub domain to example.com/def/ it then works so some how the Bind9 DNS is not updating my Records. Any Help ? Where are the ISPConfig bind9 log files ???

 

DNS Records where wrong, forget point behind domain name. Working now
