I have properly added sub-domain into DNS system.

DNS setting - https://ibb.co/e1L7KT

Apache configuration file:

<VirtualHost *:80>
ServerAdmin webmaster@localhost
ServerName demo.mydomain.com
DocumentRoot /var/www/html/mydomain

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined


I am not able to understand what is the issue exactly. I tried all the possible ways to fix this issue but unfortunately could not solve it.

Any help will be appreciated.

Hello friend!

When you say that it works occasionally, I assume you mean that you see intermittent results when loading the subdomain in browser. This is usually the result of browser cache and/or DNS propagation. Looking more into the specific values of this case would be necessary to dive any deeper.

Kind Regards,
