ILMT - Provide connection parameters for initial data source configuration fails with responding : Server API connection test failed. Server returned status 503. Ensure WebReports component is running on BigFix platform.

Components installed at 1 server RHEL 8.3, DB2 standard 11.5.5, BigFix 10.0.2, ILMT 9.2.22. A standard installation is performed (default parameters)

Webreports is running, firewall is temporarely switched off to enable Webreports communication (port 8083).

Any ideas?
