Re: Communications link failure and java.net.ConnectException: Connection timed out: connect

Hi Adriano,

"Connections: The number of connection attempts (successful or not) to the MySQL server." (http://dev.mysql.com/doc/refman/5.7/en/server-status-variables.html#statvar_Connections)

Execute "SHOW PROCESSLIST;" on the MySQL client console to check the current active connections.

The error you're getting is a communication failure between client and server. You are getting a network timeout from the Operating System, so not even reaching the MySQL server. Is this happening for every single connection? If so you must have something misconfigured.
