I am getting a faulted database after installing a security patch earlier this week. This is the error Ignition threw at me.
How can I go about re-establishing the connection between MySQL server and Ignition?
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
