The Dropbox API servers are being served with valid SSL/TLS configurations, and I'm not aware of any current service disruptions that may cause this. It sounds like there may an issue with your network connection or system. Here are some threads that may be helpful:

      If there's an issue with the official Dropbox .NET SDK, we'll be happy to look into it, but we'll need some more information. Please reply with:

      - the name and version number of the platform and SDK you are using

        I've encountered the same issue as you. I managed to fix it by adding the following lines of code

         


        ServicePointManager.Expect100Continue = true;
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

         

        before calling the dropbox functions, e.g. in the Main() function of the application.
