@imagingmaster21 I would suggest that you should move the old settings file out of the way because it’s likely not correct somehow - and rerun the installer to see if that fixes it.
mv /opt/fog/.fogsettings /opt/fog/.fogsettings-old
Here is some documentation about the fogsettings file:

Here is some documentation on changing the FOG Server’s IP address:
https://wiki.fogproject.org/wiki/index.php?title=Change_FOG_Server_IP_Address
Here’s a tool that will fix everything on the FOG Server after you change the IP at the OS level:
