Can`t connect to PostgreSQL database in Pentaho Kettle

Question

I`m trying to connect to my PostgreSQL database. What I create a connection and click the button "Test", I receive an error message. I can connect to this db via pgadmin without any problems, so it is not a connection or credentials issue

I`m using Pentaho kettle 8.3, Windows, java version "1.8.0_231"

Error connecting to database [Name] :org.pentaho.di.core.exception.KettleDatabaseException: 
Error occurred while trying to connect to the database

Error connecting to database: (using class org.postgresql.Driver)
Ошибка при попытке подсоединения.
