      <description>&lt;P&gt;Dropbox recently retired support for TLS 1.0 and 1.1. The Dropbox API servers now only support connections using TLS 1.2. You'll need to update your app/network client/environment to use TLS 1.2 in order to continue making Dropbox API calls.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;It looks like you're using &lt;A href="https://github.com/dropbox/dropbox-sdk-java" target="_self"&gt;the Dropbox Java SDK&lt;/A&gt;, so to use TLS 1.2 you'll need to update to at least v3.1.1 of that SDK (or preferably, the latest version which is currently v5.2.0).&lt;/P&gt;</description>

      <description>&lt;P&gt;&lt;a href="https://www.dropboxforum.com/t5/user/viewprofilepage/user-id/1535845"&gt;@chek534&lt;/a&gt; Make sure your platform itself also supports TLS v1.2. Some platforms/frameworks, especially older versions, may not have TLS v1.2 enabled. You may need to refer to your platform documentation for information on configuring that.&lt;/P&gt;</description>
