2020-08-19T16:02:27+08:00 localhost haproxy[12706]: Server Host2 is UP,reason: Layer7 check passed,code: 200,info: "OK",check duration: 138ms. 2 active and 0 backup servers online. 0 sessions requeued,0 total in queue.

at that time（ when the host is marked as down）， the call result will be 504 error rather than 200.

我的问题： 我已将超时设置为5000ms，为什么后端服务器＃2的响应时间超过2000ms时报告了错误？我可以增加超时来消除错误吗？
