Hello, @emirhankarasu

Could you please let me know if this has been sorted? Keep in mind that the DNS changes might take up to 48 hours due to ISP cache. Usually the DNS will propagate a lot faster, but you still need to wait for at least an hour or so. In the meantime you can check the DNS propagation using a site like https://www.whatsmydns.net/

If the DNS has propagated and the site is still not loading then you can check the Apache/Nginx and PHP error logs to see if there is a logged error as well.

The location of the Apache error log is:

/var/log/apache2/error.log

The location of the Nginx error log is:

/var/log/nginx/error.log

You can also check your PHP error log if your site is based on PHP. You can find the location of the error log from the php.ini file. Just look for the error_log line and see the exact location.

Let me know how it goes.

Regards,
Alex
