When creating my Postgres Cloud SQL instance I specified that would like to connect to it *using private IP* and chose my `default` network. 

My VM sits in the same `default` network. 

Now, I follow instructions as described here <https://cloud.google.com/sql/docs/postgres/connect-compute-engine>
and try executing 

```
psql -h [CLOUD_SQL_PRIVATE_IP_ADDR] -U postgres

```

from my VM, but get this error:

> 
> psql: could not connect to server: Connection timed out Is the server
>  running on host "CLOUD\_SQL\_PRIVATE\_IP\_ADDR" and accepting TCP/IP connections on
>  port 5432?
> 
> 
> 

Anything I am under-looking? 

P.S. My *Service Networking API* (whatever that is) is enabled.
