I am struggling to get a valid connection to a MySQL database. The SQL database is hosted on a machine which is remote from the Ignition server. I have set up a user in PHPMyAdmin with any host and global privileges. I have also turned the firewall off to see if that was blocking me. I read that MySQL 4.x is not fully supported but I should be able to connect. Does anyone have any advice?
