logstash：“握手失败”

Question

我在 logstash-forward 和 logstash 之间遇到问题，我已正确安装 SSL 证书，但出现此错误：

Failed to tls handshake with 111.111.111.111 read tcp 111.111.111.111:5000: i/o timeout

如果我使用 openssl 命令检查 SSL 可以正常工作：

# openssl s_client -connect 111.111.111.111:5000

CONNECTED(00000003)

我发现了问题： istance 之间的logstash 版本不同。升级到相同版本后，它的工作。
