Changing the Health Check Protocol

Scenarios

You can change the health check protocol as required. After the protocol is changed, the load balancer uses the new protocol to detect the health of backend servers, and it continues to route traffic to the backend servers after they are detected healthy.

During this period, the load balancer may return the HTTP 503 error code to the clients.
