@Sebastian-Roth So after taking your advice on the multiple DHCP servers, I went and checked for any possible Rogue DHCP servers using Wireshark, and I found a range that is not apart of our usual subnet, was offering and broadcasting DHCP. So the issue was rogue DHCP.

@sebastian-roth After Running the command and trying again:

Apache2 error.log:

Debian 10:
Running installfog.sh goes well until ‘go to x.x.x.x/fog/management’
The site reports http 500 error. And apache logs show:

Got error 'PHP message: PHP Fatal error:

@Sebastian-Roth Makes sense to me.
Solved for me

@Sebastian-Roth

I went through and pointed a couple to the old location, and it’s not showing Size?

@Tom-Elliott I was just if I had to reboot the machine for whatever reason that I wouldn’t have to worry about it failing. But the solution you posted has worked to get it working.
Now I just need to figure out how to get all my images to show up in the WebUI, got them all on the machine but don’t have an exported CSV from prior to database dying.

That fixed it, however after a reboot I got ‘database connection unavailable’ again.
And back to square one with:
