Same problem here. It's only happening with a couple of VMs.

UPDATE: Found a solution for my issue

For whatever reason, a couple of my VMs had the VNC protocol enabled in their options which is no longer supported.
You can verify with either:

  • Checking under the VM's configuration options: Edit Settings -> VM Options -> Configuration Parameters. Look for the option "RemoteDisplay.vnc.enabled".
  • Using PowerCLI: Get-VM "VM Name" | Get-AdvancedSetting -Name RemoteDisplay.vnc.enabled

If it's set to true, then that's the issue. I used PowerCLI to set it to false but you can do it via vcenter/vsphere:
Get-VM "VM Name" | Get-AdvancedSetting -Name RemoteDisplay.vnc.enabled | Set-AdvancedSetting -Value false

Be sure to restart the VM. This has been a thorn for one of my VMs for quite a while so it's nice to finally figure it out.
