Cluster block query when one node down.

I follow the instruction to create a citus cluster with 5 worker and set the replication factor to 3. (With docker-compose -p citus up and scaled the worker to 5)
Then created a distributed test_table as described in the official online document. Inserted 100k data to the database.
I verifyed the shards are distributed by using SELECT * FROM pg_dist_shard_placement, and successfully ran the select * from master server.

Then I was trying to test the high availability, so I shutdown one worker1 and tried the same query select * from test_table.

The expected result will be 100000 returned immediately, since there's a high availability natively built in.
The actual result is, the query will be blocked all the way to the expiration. Unless I restart the "failed" node during the blocking time.

I was expecting the cluster to automatically redirect the query to other available worker nodes with the same shards stored in worker 1.Is there anything else I have to do beyond using the "official docker images and instruction"
