I'm encountering an SSL handshake failure while trying to download firmware 
images for my SDR using the uhd_images_downloader tool.

The error occurs both when using the tool and when accessing 
https://files.ettus.com/binaries/images/ directly in a browser (any browser, - 
firefox, chrome etc)
Specifically, the SSL error that is shown in the browser is: 
SSL_ERROR_NO_CYPHER_OVERLAP

And the following is the error outputput of the uhd_images_downloader tool.

gnb@xgoss-host:~$ sudo uhd_images_downloader
