You may encounter the following issue when trying to connect to Databricks using the Qlik Databricks connector from the ODBC connector package or via ODBC system DSN:

"Error message: Please check the values for Username‚ Password‚ Host and other properties. Description: General error

ERROR [HY000] [Qlik][ThriftExtension] (14) Unexpected response from server during a HTTP connection: Could not refill buffer."

Environment

• Qlik Sense on premise all versions
• Qlik Sense SAAS

Resolution

The issue can be solved by enabling SSL using System Trust Store:

or own certificate (especially for the SAAS version):

Cause 

The cause of this behavior is that the data source requires SSL.

Followed the above and now receive the error below on QSEoW:
