I have been working on App Engine and Cloud SQL for sometime now.


Recently I have *disabled public access on my DB*. Since then I am unable 
to connect to CloudSQL using my App Engine(Both App Engine and Cloud SQL 
are in same Google Cloud Project).

The only way I am able to connect is when I add the App Engine IP on 
CloudSQL Connections Tab. But on a new deployment the IP changes, hence 
adding static IP is not an ideal answer for this.

In Cloud SQL connections tab it says the following :

*App Engine authorization* 

*All apps in this project are authorized by default. To authorize apps in 
other projects, follow the steps below.*

*Apps in this project: All authorized.* Which is not true in this case.

*Cloud SQL API and Cloud SQL Admin API are enabled.*


connection = mysql.createConnection({
  host     : 'INSTANCE_CONNECTION_NAME',
  user     : 'db_user',
  password : 'db_password',
  database : 'db_name'
});


My *app.yaml* looks like below:



env_variables:
  SQL_USER: USER_NAME
  SQL_PASSWORD: PASSWORD
  SQL_DATABASE: DB_NAME
  INSTANCE_CONNECTION_NAME: INSTANCE_CONNECTION_NAME
# [END env]

# [START cloudsql_settings]
beta_settings:
  # The connection name of your instance, available by using
  # 'gcloud beta sql instances describe [INSTANCE_NAME]' or from
  # the Instance details page in the Google Cloud Platform Console.
  cloud_sql_instances: INSTANCE_CONNECTION_NAME=tcp:3306
# [END cloudsql_settings]




*Expected:* Get a Connection. 
*Actual:* getaddrinfo ENOTFOUND INSTANCE_CONNECTION_NAME 
INSTANCE_CONNECTION_NAME:3306

Not sure why it's taking INSTANCE_CONNECTION_NAME twice.
