我在 Amazon ALB（应用程序负载均衡器）后面有一个 HAProxy，http/80 健康检查没有问题，但 https/443 却给我 503，即使该网站可用且没有问题
以下是我在 HAProxy 日志中看到的内容：
4/26/2018 3:19:47 AMApr 26 00:19:47 localhost haproxy[4494]: 172.30.139.183:31696 [26/Apr/2018:00:19:47.961] 443~ 443/<NOSRV> -1/-1/-1/-1/4 503 213 - - SC-- 2/0/0/0/0 0/0 "GET / HTTP/1.1"
这是我的 HAProxy 配置：

您需要default_backend为您的frontend 443
