Error(s) in logs when adding rim node to new Qlik Sense install such as the following:
Could not connect to database. Make sure that the database service is running and accepting connections, that database QSR exists and that the password for user 'xxxxxx.com\qlikservice' is correct
CustomAction CA_ConnectToSharedPersistenceDb returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)
Environment:
Qlik Sense Enterprise on Windows
The Rim node cannot communicate to the Central node. To resolve this, verify that the database is set up to correctly accept connections.
See How to configure Qlik Sense to use a standalone PostgresSQL database on general configuration advice.
