    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.

     

    It looks like you're using the Dropbox Java SDK, 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).
