It´s not an iReport but a KACE forum, but anyway. Where do you want to connect. to the K1000 database? Some more information would be helpful. The error message is "Connection refused". This could be a wrong username, password, database. It could also be the circumstance, that the database access isn´t allowed. Go to Settings / Security Settings and check the box "Enable database access"
