Nexmo has announced that it will disable legacy TLSv1 and TLSv1.1 protocols on August 7, 2018, to facilitate a transition to more secure encryption protocol TLSv1.2, which is now the only supported encryption protocol for HTTPS connections. The deprecation process started with a temporary shutdown of these protocols in July, followed by a two-week extension until August 21st, after which they will be permanently disabled. To ensure compatibility with Nexmo's new standard, users are advised to verify their system supports TLSv1.2 and update their software or underlying platforms accordingly, as most modern operating systems and runtime environments already support this protocol. Users can check for TLSv1.2 support using online tools or by making a GET/POST request to the verification endpoint provided by Nexmo.
