Power BI Gateway Fails when adding SSL data source

[starstruk31]

Anyone had the below issues when adding an impala connection(SSL) to the Power BI Gateway?  I added the cert to the trusted certs repo and have tested that the cert works connecting from Excel.  The below error is what I get when adding the data source to the gateway using the service.  This is an Impala connection.  Any feedback is appreciated.

From Power BI Desktop I get the following error:

@starstruk31,

Did you configue the services of Power BI gateway? After installing gateway it has it's own service account which may do not have the access to ODBC driver. You could change the service account to your Window account and check if this issue persists or not.
