VMware host keeps disconnecting...

The Problem

VMware host keeps disconnecting from vCenter which resides on the same physical machine.


Connection to the host from vCenter seems to work, but it disconnects within minutes. For example, I reconnected the host and quickly tried to update the automatic boot order details for the host and got the error:
The data service timed out because a back-end task took more than 120 seconds. See the vsphere-client-virgo.log for more details.

I *think* the firewall is not the issue
I recently upgraded to VMware ESXi 6.0
I'm using VMware vCenter Server Virtual Appliance (vCSA) 6.0b

How many hosts do you have?  Is the management network on its own vlan?

It's a very simple setup. Two hosts. No VLANs.

Host 1: On my LAN, has vCenter VM, and is ironically the one ESXi 6 host that keeps disconnecting from vCenter.
Host 2: In a datacenter offsite and out of our LAN. Not having trouble with this one.

I suppose that could be an issue since the host that's causing issues suddenly is a home built server.
Based on getzjd's suggestion, I upgraded to from ESXi 6.0.0 to ESXi 6.0.0b in hopes that might solve the issue. I also moved the SSD datastore that had ESXi installed on it from from a SATA port to a SAS port that was on the motherboard in hopes that the different BIOS for that controller was more up to date. So far it has not disconnected so I'm not positive if it was the move to SAS or the ESXi upgrade that did it. Nevertheless, thank you!
