I use google cloud services and specially VM instance to host my web-sites,
I used to KloxoMR, and usually I install it on a fresh Centos 6 or 7 with no problem. About google cloud VM I have no problem in installing Kloxo too, but I cant access to my kloxo control panel using http://ExternalIP:7778
or 7777
(https) it seems there is a problem with this two systems.
Any idea how to fix it?
