According to the error message seems that the sails js app is not reaching the Cloud SQL server.
This could happen because the Public IP of your client machine is not allowed on the authorized networks of your Cloud SQL instance.
https://cloud.google.com/sql/docs/mysql/authorize-networks
Go to the Cloud SQL Instances page in the Google Cloud Console.
Click the instance name to open its Instance details page.
Select the Connections tab.
Click Add network.
In the Network field, enter the IP address or address range you want to allow connections from. ...
Optionally, enter a name for this entry.
Click Done.
"If you find yourself encountering a "Handshake inactivity timeout" error when your Sails app interacts with MySQL, you can increase the timeout using the connectTimeout option. This is usually only necessary when queries are running side-by-side with computationally expensive operations (for example, compiling client-side typescript files or running webpack during development)."
