### Issue description ### Environment Request help without environment information will be ignored or closed. * apisix version (cmd: `apisix version`): 2.5 我们布置了两套服务，一套线上一套测试，都使用相同配置。 测试服务一直正常，线上服务却经常报错： ``` upstream timed out (110: Connection timed out) while reading response header from upstream, client: xxx.xxx.xxx.xxx, server: _, request: "POST /auth/login HTTP/1.1", ``` apisix 配置中 keepalive 时间为 60s。 请问应该怎么处理这个问题？ -- This is an automated message from the Apache Git Service.
