ESX 6 in vCenter 6 error: "A digest operation has failed"

Hi,

I'm using VMware Horizon view 6.1 on a cluster of servers running ESXi 6 build 2615704 from a base HP customized image.

However, pools of desktops are disabled showing an error that is occurred in vCenter as "A digest operation has failed".

However, enabling the pool works for a while. Then, it gets disabled after some virtual machine provisioning.
