ssl - 日志存储: "Handshake failed"

Question

我在 logstash-forward 和 logstash 之间有问题，我已经正确安装了 SSL 证书，但是我有这个错误:

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 是否正常工作:

# 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。
