we have connected multiple data sources (SQL,HANA etc) to Power BI Desktop. and we are in a process of creating datasources to On-Premise data gateway through SSL for secure data refreshes.
can you please provide documentation to SSL encrypted?
Firstly, make sure that the certificate used by your data source is within the Trusted Root Certification Authorities store of the machine running the Power BI gateway, there is an old blog stating this process.
After installing SSL certificate, add your data source within gateway.
