title: clickhouse-client get error "Timeout exceeded while reading from socket"
body: <p>I'm newbie to clickhouse, I'm trying to create a clickhouse database on my unbuntu 18.04 remote server, I follow instruction to install click house from DEB package in this link: <a href="https://clickhouse.tech/docs/en/getting_started/install/#from-sources" rel="nofollow noreferrer">https://clickhouse.tech/docs/en/getting_started/install/#from-sources</a></p>
  
  <p>after that when I run command <em>clickhouse-client</em> it shows something like this : </p>
  
  <pre class="lang-sh prettyprint-override"><code>root@busmap-api-test:~# clickhouse-client
  ClickHouse client version 20.3.5.21 (official build)
  Connecting to localhost:9000 as user default.
  Code: 209. DB::NetException: Timeout exceeded while reading from socket (127.0.0.1:9000)
