Ubuntu - apache is not working

[אורי]

Hi,

Running the command "sudo apachectl configtest" returns "Syntax OK".

Running "sudo systemctl restart apache2" doesn't respond. But a few minutes
ago it worked and the website worked. I rebooted again and now again it's
not working. The problem is that apache doesn't restart after rebooting.
