Hi,
Did you install ovirt-engine-dwh during the upgrade? Was it installed
before?
If it is installed , Can you please check the ovirt-engine-dwh.log file for
errors?
If not, It must be installed in order to view the Dashboards. It is
collecting the statistics used for the dashboards.

So I think the key here is that your database is remote. And looking at the
logs it is not finding the URL for the remote database properly. If you look
in /etc/ovirt-engine/engine.conf.d/10-setup-dwh-database.conf I suspect either
the DWH_DB_URL is missing or incorrect. It should be something like:
DWH_DB_URL="jdbc:postgresql://<remote_db_machine>:<port>/<db_name>?
sslfactory=org.postgresql.ssl.NonValidatingFactory"
db_name is usually something like ovirt_engine_history. IIRC we don't
automatically configure this file for remote databases. Let me know if the
file is missing, I can get you instructions on how to create it.
