@ultralivre Ok I tell you that FOG gets very angry if you change the IP address of the fog server after you install FOG.
I can see from your screen shot that the fog server was at 10.1.140.108 when fog was installed, and now IP address is 10.1.142.73.
If your fog server will not stay at 10.1.142.73 then you need to fix FOG settings.
Update the hidden file /opt/fog/.fogsettings with the correct fog server IP address.
Now rerun the installfog.sh script. It will load the previous answers from the .fogsettings file. No bad things will happen when you rerun the fog install script. But the fixed IP address in the .fogsettings file.
Now that the installer fixed some things you need to go to the web gui and then FOG Settings -> FOG Configuration. Now hit the expand all button. Search for the old IP address and fix with new IP address. Save your settings.
One more place you have to look is in the storage configuration. Look in the default storage node. Fix the IP address there too.
Now fog should be happy again.
