I have node-mysql client that gets "ER_NO_SUCH_USER" whenever it does an UPDATE query. All other type of query are successful but UPDATE fail.
Meanwhile in the server's log I get the standard: "[Warning] Aborted connection ... (Got an error reading communication packets)"
The client's DB user has the following permissions: GRANT SELECT, INSERT, UPDATE, DELETE, REPLICATION SLAVE, REPLICATION CLIENT, SHOW VIEW ON . TO ''@'%' IDENTIFIED BY PASSWORD ''
