Hello,

In such cases what I usually recommend is:

• First run an Apache config test to see if your config is OK:

apachectl -t

• If you get Syntax OK then the config is not the problem if there is a problem with the config you would see an error and you could further investigate based on the error

• If there are no errors with the config, then check your error log:

tail -100 /var/log/apache2/error.log

• You could also check the status of your Apache:

systemctl status apache2

With all of the above information, you should be able to get to the bottom of the case.

Regards,
Bobby
