Getting error,The request was aborted: Could not create SSL/TLS,while uploading file using save_url

The error message you shared indicates an issue at the transport layer, so the particular API endpoint, Dropbox file, or async job shouldn't matter. (Those are all only used after the secure connection is negotiated.)

The Dropbox API servers are currently being served with valid TLS configurations though (e.g., see the SSL Labs report for api.dropboxapi.com and for api.dropbox.com).

Is there anything that may be interfering with your network connection to *.dropboxapi.com or *.dropbox.com? For instance, any proxy, firewall, or other security software?

Also, the Dropbox API servers currently support TLS 1.0 or higher, so make sure your client isn't trying to use an older protocol, such as SSL 3.0, for instance.
