A large number of the following logs appear in TiKV. What error is this, and which components are interacting incorrectly?

Is the network normal for the handshake protocol exception?

Is this a test environment or production? Is business access normal? Is it only one TiKV reporting this error or all of them? Are there any abnormal logs from other components? How is the monitoring information for the cluster component’s Grafana?

Please investigate all these aspects and organize the current status of the cluster, otherwise, it will be difficult to analyze the problem.

Is the SSL protocol error caused by an upgrade of a component?

Production cluster, more than one cluster reported this error, OpenSSL has not been upgraded.

Is there any impact on business access, and what is the cluster latency like?
