Data source refused connection

ERR.DS_API.DB.SOURCE_CONNECT_ERROR

Error loading data.

This error means that a connection to the database could not be established.

To fix the error, check the connection settings:

• Check that the information specified in the connection is correct: Hostname, HTTP interface port, Username, and Password.
• If the specified port only works over HTTP, disable the HTTPS connection option.
• If the host list contains only one host, enter all the cluster hosts separated by commas in the Hostname field.
