In Tenant App 2.4.x and 2.5.x, the default password of Cassandra was used to communicate with the plugin and the DB container. After the release of 2.6.x, the usage of the default password was removed due to security concerns so when you upgrade from 2.4.x,2.5.x release to 2.6.x and above release, there is a conflict of old plugin communication with upgraded APP and DB container.
