Kubernetes pods not able to connect to the hosted postgres instance

I was following the Django kubernetes series (How To Deploy a Scalable and Secure Django Application with Kubernetes | DigitalOcean

But I ran into a problem where the Django app that works fine in Docker can’t no connect to the digital ocean postgres after being deployed into Kubernetes. I then did some further exploration and launched postgresql-client pod, and I can’t seem to connect from it either, even though name lookup and so on seem to work. When trying to run this

psql -p 25060 -U sammy -d polls -h databasenamestring-0.b.db.ondigitalocean.com

from inside a pod it hangs, while the same command works from both a linuxvm droplet and also from my home comp. Also the name lookup for the database does work, nor does it work if I give the host ip address directly.

And of course most critically, the Django app can’t connect the database but hangs whenever it tries to access the DB in the back.
