I am unable to connect to Cloud SQL from Google App Engine. I am not sure what the problem is but I came across a note from an instruction stating this is a performance Cloud SQL in alpha stage and connection from Google App Engine are not excepted. Is this the problem I am unable to connect to Cloud SQL? Can anyone explain me the the note? The screenshot of the note is below
Connecting from App Engine is not yet supported for Second Generation instances. You will need to create a First Generation instance if you must connect from App Engine.

I have developed an application in asp.net core EF, with MySql DB. Application is deployed on Google Cloud App Engine. I am trying Connecting Google Cloud App Engine application to Cloud MySql under same cloud project. Locally i am able to connect this database, but when deployed on google cloud i am getting error
MySqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
MySql.Data.Common.StreamCreator.GetTcpStream(MySqlConnectionStringBuilder settings)
MySqlException: Unable to connect to any of the specified MySQL hosts.**
MySql.Data.MySqlClient.NativeDriver.Open()
I am using below connecting string
"DefaultConnection": "host=33.444.**.**;port=3306;database=mYdb;user=root;password=pASS"

Take a look at the "Connecting from App Engine" page here on the Cloud SQL docs. You need to enable the Cloud SQL server in your app.yaml, and then connect via 127.0.0.1:5432.
I have a Google App Engine application that operates perfectly when run locally using localhost:8080, but after I deploy to the cloud using gcloud app deploy, I receive the following error:
Warning: PDO::__construct(): MySQL server has gone away in /base/data/home/apps/s~fileabcd/20190320t221240.123456737151234567/gac_abcd.php on line 7

Any ideas why this is happening?
I discovered the reason why my Google App Engine (GAE) application functioned properly on localhost, but threw a MySQL server has gone away error after being deployed to [PROJECT-ID].appspot.com.
The reason is because my application was connecting to a Cloud SQL instance in a different project, and in order to do this you must grant the default appengine service account ([PROJECT-ID]#appspot.gserviceaccount.com) one of the following IAM roles:
Cloud SQL Client
Cloud SQL Editor
Cloud SQL Admin
After I added the App Engine default service account as a Cloud SQL Client Role in the project containing the Cloud SQL instance, everything worked perfectly.
From the Cloud SQL documentation.
I'm running into an issue in re-using my connection string (resolved here ... Cannot connect to Google Cloud SQL using SSL + Golang from Google App Engine ...) from connecting to a Google Cloud SQL generation one instance while trying to connect to a generation two instance. I'm receiving this error: TLS requested but server does not support TLS
I can't figure out how to get around this, and the documentation is pretty scarce.
I caught the fact that Instance connection name follows a different structure on generation two, but that doesn't seem like the issue. Has anyone solved this? I'm connecting from Golang.
MySQL level SSL is not currently supported between App Engine Standard Environment and Cloud SQL Second Generation instances.
Communication between App Engine Standard Environment and Cloud SQL is already encrypted so using MySQL level SSL does not add a lot of value, though I can understand that doing application level SSL can add some peace of mind since what happens between Cloud SQL and App Engine is opaque.
I'll try to see if this is something we can change.
When trying to connect my Google App Engine to my Google Cloud SQL Instance (Second Generation), I cannot find the "...Authorized App Engine applications section..." (https://cloud.google.com/appengine/docs/php/cloud-sql/#PHP_Build_a_starter_application_and_database).
Am I just blind, or does this not exist anymore?
If it doesn't exist, how does one connect a Google App Engine to a Google Cloud SQL (Second Generation)?
Please review the limitations of Google Cloud SQL Second Generation.
Because Cloud SQL Second Generation instances are in beta, the following features are not available:
Service Level Agreement (SLA)
MySQL 5.5
MySQL 5.6 is supported.
Google App Engine connectivity. Connectivity is supported for other clients, including Compute Engine, Managed VMs, Container Engine, and your workstation.
....
I'd like to mention that although Google App Engine connectivity is not yet supported for the Cloud SQL Second Generation like the way is supported for Cloud SQL 1st Gen, however this doesn't mean that you cannot use Cloud SQL 2nd Gen with your App Engine applications.
You can use access control model which is described in this article as used for other applications. Since IP address of your App Engine application will be not a static address, you will need to authorize 0.0.0.0/0 IP range as an allowed network and use Allow only SSL connections feature of the Cloud SQL to allow only SSL connections. Configure SSL and generate keys and client certificate for your application and establish a secure connections using SSL.
Right now, App Engine cannot be used with CloudSQL Gen2. It should be possible once the CloudSQL Gen2 graduate to General Availability but right now, if you need to use it with App Engine, you'll need to stick with CloudSQL v1
I would like to use the application identifier access control method for allowing my app engine service connect to a Cloud SQL database. The app engine service is written using dart with sqljocky.
In the Developers Console, Storage, Cloud SQL, db instance, Overview tab, there is a link titled "How to connect to your Cloud SQL instance". There, I only see sample code for doing this in PHP, Java and Python. I've tried to find an analogous implementation for dart with no luck.
Can anyone suggest an approach for doing this?
