How to set up postgraphile on a digitalocean hosted postgres db

I am trying to setup postgraphile on an already existing DigitalOcean hosted postgres db by following the instructions here https://www.graphile.org/postgraphile/quick-start-guide/ “npx postgraphile -c ‘postgres://user:secret-0.b.db.ondigitalocean.com:25060/defaultdb?sslmode=require?ssl=true&sslrootcert=ca-certificate.crt’ --watch --enhance-graphiql --dynamic-json” but it fails on the very first trial with a connection time out error reproduced below. PostGraphile v4.12.3 server listening on port 5000 :rocket:

‣ GraphQL API: http://localhost:5000/graphql ‣ GraphiQL GUI/IDE: http://localhost:5000/graphiql ‣ Postgres connection: postgres://doadmin:[SECRET]@user.b.db.ondigitalocean.com:25060/defaultdb (watching) ‣ Postgres schema(s): public ‣ Documentation: https://graphile.org/postgraphile/introduction/ ‣ Node.js version: v14.17.0 on linux x64 ‣ Join Simon Elliott in supporting PostGraphile development: https://graphile.org/sponsor/

A serious error occurred when building the initial schema. Exiting because retryOnInitFail is not set. Error details:

Error: connect ETIMEDOUT 46.101.73.34:25060 at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1146:16)

it seems like a permission issue of the server not allowing connections from the location.

How can I resolve this?
