Hello,
We have two rke2-servers on two RHEL 8 machines, and after a reboot on one of them, we started getting rke2[3715192]: {“level”:“warn”,“ts”:“2024-05-25T17:51:42.460556+0100”,“logger”:“etcd-client”,“caller”:“v3@v3.5.9-k3s1/retry_interceptor.go:62”,“msg”:“retrying of unary invoker failed”,“target”:“etcd-endpoints://0xc0004aa380/127.0.0.1:2379”,“attempt”:0,“error”:“rpc error: code = DeadlineExceeded desc = latest balancer error: last connection error: connection error: desc = "transport: authentication handshake failed: tls: failed to verify certificate: x509: certificate signed by unknown authority"”}. The other machine we didn’t reboot it, and we are not getting the error there. Because of this we can’t do a helm upgrade as well and when the kubernetes tries to download images it gives the certificate error as well.
Does anyone have any hint what might be?
Thank you.
