Error certificate in Postgres Data base

Hi all,

I'm using a Postgres Data base, I am having a problem in the Power Bi service with a Postgres database.
In the Desktop version I have solved it by following the instructions, but when it comes to uploading it to the Powerbi service, when it comes to refreshing the information it returns the error:

"The remote certificate is invalid according to the validation procedure"

My server is a Linux and a Postgres Data Base, any idea how to fix that?

Thanks

Eduard
