[google-cloud-sql-discuss] Re: Can't connect to Cloud SQL from Compute Engine

Hello Ram,

According to MySQL documentation [1], this error is thrown when a network connection has been refused. If you are using a private IP, then make sure your Compute Engine instance is in the same region as the Cloud SQL instance and on the network configured for a private connection. You can follow these guidelines [2] for private IP connection, or these steps [3] for public IP. If you have enabled SSL on the instance, here is how to set this up for proper connections [4].

Hi,

I am receiving "ERROR 2003 (HY000): Can't connect to MySQL server on " on connecting to Cloud SQL from Compute Engine. Both are in the same project. I have added compute engine IP Address to the allowed connections.
