I've just deployed another ISPCOnfig for a friend. So happy. However the ISPConfig Monitor page complain about an issue with the web service. He claim that the service is down. I have no idea why. I mean, everything's fine. I can't find any error anywere. I've create a few sites and they seems to load properly. What is the logic used by ISPConfig to determine it the web-Server service is running ? Is there a trace that can be looked at for the monitoring server wich give more information than "down" I think that it can be related to the fact the I had to enter my IP address in every Apache directive related to LISTEN. So instead of LISTEN 80 I have LISTEN 188.8.131.52:80. I'm on Debian Jessy with ISPConfig 184.108.40.206p8. PHP is 5.6.17. Apache 2.4.10. I have one master that is use for the web interface, MySQL and web sites. Another machine for DNS and the third one for mails.
