只看到dashboard自己发自己的心跳,列表只能看到自己,无语了不知道为什么


Reproduce the reported setup with sentinel-dashboard-1.8.8, the Spring Cloud Alibaba Sentinel 2021.1 dependencies, and the SimpleHttpHeartbeatSender logs. Start at the heartbeat request to 192.168.30.39:8719 and the dashboard registration path; done means identifying why the request returns HTTP 400 and confirming that the application appears in the dashboard.
