I have an etcd cluster with a number of 3, only one works

[Gezx]

when I use:
kubectl get cs
it shows as follows:

Warning: v1 ComponentStatus is deprecated in v1.19+
NAME                 STATUS      MESSAGE                                                  ERROR

etcd-1               Unhealthy   Get "https://175.31.2.124:2380/health": unexpected EOF
etcd-2               Healthy     {"health":"true","reason":""}

the error is :

Nov 30 16:28:39 master etcd[3894695]: WARNING: 2022/11/30 16:28:39 [core] grpc: Server.Serve failed to create ServerTransport:  connection error: desc = "ServerHandshake(\"175.31.2.123:60108\") failed: tls: first record does not look like a TLS handshake"

If anyone knows what causes this error?

you need to check the tls-file configure
