CMK version: 2.2p5

The forum search did not find any so i assume this is the first entry on this :slight_smile:
A few days ago i had a support call where a site won’t start.
Error:

So Nutanix Guest Tools starting before Apache, blocking port 5000 and preventing the site from being started.
Note: Site was there first, tools have been installed after migration from ESX to AHV.
Changing port to 5001 solved it.
