Clickhouse code 32 DB::Exception: Attempt to read after eof

I created a dictionary on Clickhouse using the following script:

CREATE DICTIONARY IF NOT EXISTS default.testDICT
(
-- attributes
)
PRIMARY KEY DATETIME, SOMEID, SOMEID2
SOURCE(CLICKHOUSE(HOST 'localhost' PORT 9000 USER 'default' PASSWORD '' DB 'default' TABLE 'test'))
LIFETIME(MIN 0 MAX 300)
LAYOUT(COMPLEX_KEY_HASHED())


The table test has approximately 19 000 000 rows.

And when I try to execute a select

SELECT * FROM testDICT


, which also loads the dictionary if I understood well, it sends me the following error:


Exception on client:
Code: 32. DB::Exception: Attempt to read after eof: while receiving packet from clickhouse-server:9000

Connecting to clickhouse-server:9000 as user default.
Code: 210. DB::NetException: Connection refused (clickhouse-server:9000)




Do you know what it means and also how can I correct it?
