Constraint Violation Exception when installing Brightcove Connector

Question

I am trying to install Brightcove AEM connector brightcove_connector.ui.apps-5.5.1.zip. I have uploaded the package and trying installing in author using admin account and installation is failing due to ConstraintViolationException. Below is the complete exception message. Any idea why its happening? do we need to open up firewall rule for brightcove for installation? We are using AEM 6.4.1 version and its in house environment
