Docker Application with Managed Database

I have a Python (FastAPI) application running on the app platform within a docker container which I’d like to connect to a managed database. At the moment, I’m only using a dev database.

When I deploy my application, the message which pops up is as follows:

asyncpg.exceptions.InvalidAuthorizationSpecificationError: no pg_hba.conf entry for host "167.99.147.79", user "db", database "db", SSL off

I’m using sqlalchemy to make the connection, but it appears as though I’m making the conscious effort not to use SSL.

Default connection options try SSL first; when I require it, it still returns this message.

Any leads? I imagine the cause is that the server may not be set up for SSL from the get-go, but I’m stumped on proving this to myself.
