You need to [upgrade to TSLv1.2](https://www.google.com/search?q=tls+1.2&oq=tls+1.2&aqs=chrome..69i57j0l5.2743j0j7&sourceid=chrome&ie=UTF-8) and then it will work. Apologies for not making an announcement about this. We will add documentation shortly.

> We were experiencing a similar issue after the updates this past weekend. The client we were using was based on an older version of Java 1.7 that did not have TSLv1.2 support. Upgrading and using TSLv1.2 appears to have corrected our issue

Thanks,  
Tommy
