Unable to connect to Galera cluster "[addresses]" with the username "bobman" Error 2002: Operation timed out

Error 2002 is not handled. And when this happens, the server is being removed from the pool. Instead, double the timeout value for the next connection attempt. Alternatively, increment connection timeout by a set value (2 seconds?)
