Server was unable to process request. ---> MySqlException raised in OpenConnection, 
Host is blocked because of many connection errors; 
unblock with 'mysqladmin flush-hosts' 

--- End of internal exception stack trace ---

Do you have an idea why this exception appears?

Answer 1

You can try setting a higher value for max_connections and max_connect_errors in my.cnf.

You can see more information about this error on blocked-host and communication-errors
