title: How to fix Microsoft ODBC Driver 17 for SQL Server ssl_choose_client_version:unsupported protocol on debian?
body: <p>I have installed sql server developer edition on my debian 10 linux, and I can connect to my localhost with no problem. I have a database which I could connect to it by a specific connection, for this purpose I have to connect to a gateway through pptp vpn, but when I want to connect with this command at my terminal:</p>
  <pre><code># sqlcmd -S &lt;server name&gt; -U &lt;username&gt; -P &lt;password&gt;
  </code></pre>
  <p>I face with these messages:</p>
  <pre><code>Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : SSL Provider: [error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol].
  Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : Client unable to establish connection.
  </code></pre>
  <p>Do you know how can I fix it?
  Thanks.</p>
