Horizon View 7.10 + RHEL 7.7 virtual machine = black screen when connecting

I've got a ESXi 6.7 virtual machine running Redhat Workstation 7.6.

Horizon view agent installs without issue and regsiters with the connection server.

RHEL VM has been integrated with AD using SSSD.   Domain users can log in via SSH without issue.

I can establish a session from the connection server but all I get is a black screen.   Black screen sits for about 30 seconds and then terminates.

I've tried this with HZ 7.9 and 7.10. 

Also re-installed vmware tools multiple times (with re-installing the agent after the tools are installed)

Also tried with a Nvidia GPU attached (passthrough using quadro driver) and without a GPU attached.   I get the same behavior.  

firewalld/iptables is disabled.

Thanks in advance
