我在C*日志和所有节点中看到以下异常。这是否与系统库等有关?顺便说一句，所有节点上安装的openSSL都是相同的，并且有效的证书都在适当的位置。

有人遇到过这个吗?请解释一下。
感谢根据我的经验，SSLHandshakeException警告最常见的原因是客户端在没有SSL证书的情况下连接到集群。
考虑这样的情况:您启用了监视，代理/守护进程/进程试图连接到加密的集群，但没有使用SSL连接。这也可能发生在客户端应用程序(通常是微服务)连接到集群没有SSL。
您需要识别未正确配置的连接到集群的客户端/应用程序。
请注意，消息记录在WARN级别(而不是ERROR)，因为这对集群的操作没有影响。只有配置错误的客户端/应用程序受到此问题的影响。干杯!
