can't connect to MySql from Java remotely

I tried connecting to MySQL from Java, Class.forName(“com.mysql.jdbc.Driver”).newInstance(); java.sql.Connection conn1 = null; conn1 = DriverManager.getConnection(“jdbc:mysql://mydomain.com/databaseName”,“mySQLusername”,“mySQLPassword”); conn1.close();

com.mysql.jdbc.PacketTooBigException: Packet for query is too large (4739923 > 1048576). You can change this value on the server by setting the max_allowed_packet’ variable.

I changed the max_allowed_packet = 16M, but it’s still showing the same error. I tried to connect to local mysql database and a friend’s machine on the intranet, it worked. Could that be a digitalOcean problem

Thanks in advance.
