At this point I'd go to engine VM and remove host from the postgres DB
manually.
A bit of a hack, but...
ssh root@<engine>
su - postgres
cd /opt/rh/rh-postgresql10/
source enable
psql engine
select vds_id from vds_static where host_name='myhost1.mydomain.com';
select DeleteVds('<vds_id from prev statement>');
Of course, keep in mind that editing database directly is the last resort
and not supported in any way.
