Re: [google-cloud-sql-discuss] Can't connect from AppEngine to CloudSql

Hello sorry for late reply.

I tried with the recommended method. It now works. (with lib: mysql-socket-factory-connector-j-6)

However HikariConfig does not work. It continuesly throws exception. It only works when I connect normally (Using JDBC driver)

Do you have any idea why? 

DataSource pool = new HikariDataSource(config); //(Does not work)
conn = DriverManager.getConnection(url); //works

Both have the same configs and urls.


Thanks and regards.

How do you connect to your instance? Is it the same as described in https://cloud.google.com/sql/docs/mysql/connect-app-engine, or do you connect using your Cloud SQL instance's IP?

Hello, 

I have simple Java application. I deployed it to the AppEngine.

When I try to connect to the MySql of GCP CloudSql, I get connectoion error.
It says "Apps in this project. All authorized." 

My java app and CloudSql are in the same GCP app. 

When I add all networks ("0.0.0.0/0"), then it works. However I don't want to add this. 

What could be the reason? Is there something extra that I have to do in order to connect from AppEngine? 

Thanks and regards.
