[google-cloud-sql-discuss] Re: 2nd gen flexible environment "Lost connection to MySQL server at 'reading initial communication packet'"

I'd suggest the following:

- Check the CloudSQL instance logs.

- Check that all apps in the project are authorized under Access Control -> Authorization in the Cloud Console.

- Try a re-deploy of the application.

Hello,

I am unable to connect to 2nd gen google cloud sql instance from google app engine instance. When I try to connect it simply fails with 

Lost connection to MySQL server at 'reading initial communication packet'

 

The weird thing is that I have another GAE service in the same project which successfully connects to this sql instance via socket. Here is the piece of configuration 

beta_settings:
  cloud_sql_instances: xxxxx-test:us-central1:xxxxx-development

Socket is available

root@4badd097c0d5:/app# ls -lA /cloudsql/xxxxx-test\:us-central1\:xxxxxxx-development srwxrwxrwx 1 root root 0 Jun 10 11:51 /cloudsql/xxxxx-test:us-central1:xxxxxxxx-development

This is not related to my app's code because 

root@4badd097c0d5:/app# mysql --socket=/cloudsql/xxxxx-test\:us-central1\:xxxxxxx-development

ERROR 2013 (HY000): Lost connection to MySQL server at 'reading initial communication packet', system error: 0

Any advice how to proceed here?
