'Error on remote system: 0 'when using FederatedX on MariaDB

I am using MariaDB 10.1 64x and experiencing error with FederatedX engine. First, I create an server:

CREATE SERVER AAA_fed
Foreign data Wrapper mysql_1
OPTIONS (
    User 'user1',
    password 'password',
    host 'x.x.x.x',
    Port 3306,
    database 'AAA'
    );

and then create federated table using connection to the server. 

CREATE TABLE table1 
ENGINE = FEDERATED 
CONNECTION='AAA_fed';

The table is created successfully, but when selecting data from it, it response an error:

Error Code: 1296. Got error 10000 'Error on remote system: 0: ' from FEDERATED

Does anyone know the solution to this? I keep searching but cannot find the answer. Thank you.

There is also one reason for this error. Which occurs when you created a federated table, that pointing to a table in the same server.

WRAPPER should be a recognized connection protocol.

Example:

MariaDB [(none)]> SELECT VERSION();
+--------------------------+
| VERSION()                |
+--------------------------+
| 10.1.14-MariaDB-1~xenial | -- 64 bit
+--------------------------+
1 row in set (0.00 sec)

MariaDB [(none)]> DROP DATABASE IF EXISTS `BBB`;
