Update:

It is a known issue comfirmed by engineers:

Power BI customers using the September(SU09) Gateway or Power BI desktop with an on-premises SQL data source that has a self-signed certificate and "Force Encryption" set to Yes may experience issues with reports using Import or Direct Query modes and see the message "A connection was successfully established with the server, but then an error occurred during the pre-login handshake". As a workaround, customers can install a previous version of Gateway and Desktop versions as needed. Engineers have identified the root cause and an ETA for a fix will be provided soon.
