Hi,
did you try to setup by command line or by cockpit?
I think i had the same problem when using the command line installer and
selecting static address for the HE. When using cockpit all worked,
but i noticed that cockpit asked additionally for a netmask...
I not tried again with command line installer, but i think when giving
the static address for the HE one should add netmask (e.g. /24).
Maybe this helps.
