PowerBI not connecting to postgreSQL Server

I am running a PostgreSQL server on my local Apple silicon, I am having issues connecting PowerBI running on Parallels to the database server.

I get an unable to connect message:

Details: An error happened while reading data from the provider: 'No connection could be made because the target machine actively refused it'

There doesn't seem to be any guides or tutorials for this particular issue/setup.

If anyone could even just point me in the right direction, that would be great.
