[BUG] 应用无法找到Sentinel dashboard

Sentinel 是启动成功的,版本是1.8.8

应用这边提示无法链接到Sentinel 控制面板
Sentinel dashboard heartbeat message can't be sent to the dashboard servers [Endpoint{protocol=HTTP, host='localhost, port=8080}] one of them can't be connected

Start by reproducing the application-to-Sentinel dashboard connection using the endpoint shown in the error, including localhost:8080, and compare it with the running dashboard's actual address. Done means the heartbeat reaches the Sentinel 1.8.8 dashboard without the connection error.
