Hello Dejan,
I have solved the problem described below by
adding the parameter
statusurl="http://127.0.0.1/server-status"
to the apache resource and by replacing this line
Listen 10.5.75.83:80
by the line
Listen 80
in the file /etc/apache2/ports.conf. So we enabled
the Apache to listen on all IP addresses. Thank you.
Best regards,
Michal Vyoral
