Connect to Postgres for live data

Hi,
I wanted to connect to postgres DB from Power BI. I shoud be able to get live data from postgres. When I am trying to connect to Postgres db, I am getting the following error:

An error happened while reading data from the provider: 'The remote certificate is invalid according to the validation procedure.

Any suggestions to get live data from postgres db to power BI would be helpful.

Thanks in advance.
