Troubleshooting database connection issues
Web Modeler Self-Managed is available to enterprise customers only.
You try to start Web Modeler, and encounter issues with the database connection.
Secure connection to standard PostgreSQL
Refer to the database configuration guide for details on how to configure a secure connection to PostgreSQL.
Secure connection to Amazon Aurora fails
You configured a custom SSL certificate in your remote Amazon Aurora PostgreSQL instance and want Web Modeler to accept that certificate.
Add Amazon Root CA to trust store
By default, the Java version used by modeler-restapi ships with the Amazon Root CA.
If you passed a custom trust store to modeler-restapi's JVM process (e.g. via JAVA_TOOL_OPTIONS as described in
the Zeebe connection troubleshooting guide),
ensure the Amazon Trust Services CA are in modeler-restapi's trust store (see the
Amazon Aurora documentation).
IAM authentication against Amazon Aurora fails
You switched from standard username/password authentication to IAM authentication and Web Modeler can't obtain a connection to the database.
Ensure the IAM account has all privileges to the Web Modeler database
After switching from standard username/password authentication to IAM authentication, privileges to Web Modeler's database might still be associated with the old username. Ensure the IAM account has all privileges to the Web Modeler database.
