SSL23_GET_SERVER_HELLO:tlsv1 警告内部错误

Question

目前运行遇到类似问题，但 none 的解决方案有帮助

https://askubuntu.com/questions/649000/openssl-curl-error-ssl23-get-server-hellotlsv1-alert-internal-error

我无权访问服务器配置，因为这只是一个普通的 Cloudfront+S3 设置。

root@xxx:~# openssl s_client -connect tracking.kairion.de:443 -servername tracking.kairion.de
CONNECTED(00000003)

Curl 返回类似错误

root@xxx:~# curl 'https://tracking.kairion.de/kairion.gif' -v

错误可在至少两台服务器上重现：

openssl 1.0.1t-1+deb8u5 (jessie)
openssl 1.0.1t-1+deb7u1 (wheezy)

但适用于

openssl 1.0.2j-1 (stretch)

有趣的是，有时它可能会工作一个小时，然后会失败一个小时。

今天发现问题，与cloudflare有关。

由于我为此子域禁用了 cloudflare，因此它可以正常工作。

似乎 cloudflare 有时从 cloudfront 返回正确的 CNAME，有时返回 cloudflare IP。只要它直接返回 cloudfront，SSL 就可以工作，当它返回 cloudflare IP 时，SSL 就会失败。
