LAPPStack remote mysql won't connect

Hello Guys,

I've spawned up a LAPPStack server on the AWS cloud and I need to connect my PHP application to a remote MySQL that we have hosted elsewhere.

However, I get a 'Error establishing a database connection' thrown by PHP.

I have checked the connection from other remote sites and it appears to work just fine. Is there any configuration on the BitNami LAPPStack image which would be blocking this outbound port (3306) for some reason?

Thanks,

Robert
