Cant connect with cloud_sql_proxy over tcp - google-cloud-sql

Question

I created a Cloud SQL instance and am trying to connect from my laptop running OSX El Capitan.
I followed the instructions for creating a proxy to run the proxy. I am able to connect if I use a socket file as follows:
sudo ./cloud_sql_proxy -dir=/cloudsql -instances=my-project:us-central1:mysql-instance -credential_file=mycredentials.json
mysql -u root -p -S /cloudsql/my-project:us-central1:mysql-instance
Now I'd like to connect to the Cloud SQL instance from a local python application. So I tried creating the proxy over tcp using =tcp:3306 and testing using the mysql client as follows:
sudo ./cloud_sql_proxy -dir=/cloudsql -instances=my-project:us-central1:mysql-instance=tcp:3306 -credential_file=/web/visi/api/resources/keys/visi-staging-ec040759d57a.json
mysql -u root --host 127.0.0.1 --password
But Im getting this error:
2016/04/06 23:09:58 Got a connection for
"my-project:us-central1:mysql-instance" 2016/04/06 23:09:59
to "my-project:us-central1:mysql-instance" via

Answer 1

Try specifying --skip-ssl as an option to your mysql client.
We have a fix for this in progress and should be rolled out in the near future.
The reason this happens is that we reject connections over the proxy that request MySQL SSL. The connection between the proxy and Cloud SQL is already done over SSL so there's no need to use SSL at the MySQL level.
