haproxy 1.5特定源IP地址在haproxy日志中显示<NOSRV> 503 SC

我有一个不寻常的问题（正如每个人在这个网站上做的那样） . 我在端口80和443上监听HAProxy . 我正在将SSL加密卸载到HAproxy并将所有流量传递到我的Web服务器端口80.我的HAProxy服务器前面有一个防火墙，NAT规则指向我的内部侦听IP地址HAProxy的 . 我们在端口443上通过SSL获得了一条不寻常的503消息，用于随机IP源地址 . 其他随机IP地址在SSL上工作正常 . 我们的服务是一个API，大多数流量通过，但很小的百分比得到503 .

这是一个有效的HAProxy日志条目，它不起作用：

localhost haproxy[5404]: XXX.XXX.XXX.XXX:54787 [15/Jun/2016:22:46:57.592] https_in_ssl~ http_www2/web1 32/0/0/232/264 200 747 - - ---- 5/4/0/1/0 0/0 "POST /webservices/ourService.asmx HTTP/1.1"

不工作：

localhost haproxy[5404]: XXX.XXX.XXX.XXX:55494 [15/Jun/2016:22:46:39.514] https_in_ssl~ https_in_ssl/<NOSRV> -1/-1/-1/-1/227 503 212 - - SC-- 3/2/0/0/0 0/0 "POST /webservices/ourService.asmx HTTP/1.0"

我注意到的一件事是前端和后端在不工作的日志条目中是相同的 .

这是我的配置文件：
