If you find the following error message in the installation logs: "psql: FATAL: no pg_hba.conf entry for host [ipv4 or ipv6]", it means the database needs to be configured.
Possible cause
The database is not configured to allow connection from that IP address or range.
Proposed action
Add an IP address or range in the Shared Persistence configuration file, see Shared persistence configuration file syntax, or in the installation UI, see Installing Qlik Sense in a multi-node site.
