Power BI Service can't connect to Postgres.

So, I have a Postgres database that is avaialable on AWS. I have connected to the database using the Postgres connector in "Get Data" in Power BI desktop and unchekced the "Encrypt Connection" box. This allowed me to connect build reports which I then published to an organization workspace used by my company.

However, I am unable to see any data on the reports published and upon checking getting the "remote certificate invalid error".

Please assist on this matter.
