[google-cloud-sql-discuss] Cannot connect using gcloud

I can list the databases in my Cloud SQL instance but I can't connect to it.

gcloud beta sql databases list --instance=dbinstance

NAME CHARSET COLLATION

information_schema utf8 utf8_general_ci

main utf8 utf8_general_ci

mysql utf8 utf8_general_ci

performance_schema utf8 utf8_general_ci

I can see my local machine being added to the authorisation list via the console. But it's failing to connect:

gcloud beta sql connect dbinstance --user=root

Whitelisting your IP for incoming connection for 5 minutes...done.
Connecting to database with SQL user [root].

Enter password:

ERROR 2003 (HY000): Can't connect to MySQL server on 'x.x.x.x' (110)

It isn't configured to use SSL. Actually, this is a newly created instance so I'm happy to try any suggestions regardless of how drastic they are. I can connect in this way from the gcloud command line within the console.
