FWIW: I got the same error number and it was due to an expired certificate, so this is another potential source for the issue.
FWIW：我得到了相同的错误号，这是由于证书过期，所以这是该问题的另一个潜在来源。

There is a bug on iOS 8 when using a certificate with hash function SHA512, better use the SHA256. I stuck with this error for weeks.
在 iOS 8 上使用带有哈希函数 SHA512 的证书时存在一个错误，最好使用 SHA256。我被这个错误困扰了好几个星期。

Normally when I get CFNetwork SSLHandshake failed -(*) Its because of my local wifi network (device is connected to network but not the internet)
通常当我得到 CFNetwork SSLHandshake 失败 -(*) 这是因为我的本地 wifi 网络（设备已连接到网络但未连接到互联网）
Try it again on another network (3G is the quickest solution for me)
在另一个网络上再试一次（3G 对我来说是最快的解决方案）
