Thanks for the suggestion. That finally solved the issue!
the line in /etc/tigervnc/vncserver-config

$interface = "192.168.x.xxx";

MUST come BEFORE the line

$localhost = "no"

I was always putting the $interface line after the $localhost line. In that
case, it just binds to localhost. This was not clear in the man pages.
