Machines are deleted after provisioning

Hi

I’ve created a Horizon environment and created an Automated Desktop Pool

The funny thing is, that when the provisioning starts, the replica machine is created in vcenter, the virtual desktops are created and immediately after that everything gets deleted!

This is what is shown in vcenter tasks:

I have 3 virtual servers:

vCenter appliance 6.0.0 -3040890

connection server 6.1.1

composer server 6.1.1

any ideas?
