Resolved: Server State Overview reports web service offline I have a new server setup using nginx and debian wheezy. It is showing the web server service offline, even though it is actually online. I suspect this may have to do with my IP address configuration. There are two IP addresses set up on the machine. Both are in /etc/network/interfaces Code: # This configuration file is auto-generated. # # WARNING: Do not edit this file, your changes will be lost. # Please create/edit /etc/network/interfaces.head and # /etc/network/interfaces.tail instead, their contents will be # inserted at the beginning and at the end of this file, respectively. # # NOTE: it is NOT guaranteed that the contents of /etc/network/interfaces.tail # will be at the very end of this file. # # Auto generated lo interface auto lo iface lo inet loopback # Auto generated venet0 interface auto venet0 iface venet0 inet manual up ifconfig venet0 up up ifconfig venet0 127.0.0.2 up route add default dev venet0 down route del default dev venet0 down ifconfig venet0 down auto venet0:0 iface venet0:0 inet static address aaa.bbb.ccc.19 netmask 255.255.255.255 auto venet0:1 iface venet0:1 inet static address aaa.bbb.ccc.195 netmask 255.255.255.255 Only the main IP is in /etc/hosts Code: 127.0.0.1 localhost.localdomain localhost # Auto-generated hostname. Please do not remove this comment. aaa.bbb.ccc.19 web.fakedomain.com web ::1 localhost (I changed the first numbers of the IP to letters in this post for security reasons) In the ISPConfig interface under System > Server IP Addresses I only have the main IP entered. I did have both and removed the second to see if it would fix the issue. What is the proper way this should be setup for the service monitoring to work properly? On the initial setup, there was nothing in System > Server IP Addresses. It is only when I added them that the error occured. Please let me know if further information such as log files or nginx config is needed. (and where they are located) Thanks in advance.
