To troubleshoot this issue, check the error logs for any Data Source connection issues.

If the Data Source is a database, ensure that the driver jars are available in both Identity Server and Administration Console. If the Data Source is a secure LDAP connection, ensure that SSL certificate of the LDAP directory is imported in Identity Server’s trust store. Update all Identity Servers.
