Letsencrypt 在非标准端口上吗？

我遇到了一个无法解释的奇怪现象。我正在运行一个带有 letsencrypt 的 nginx 和一个 Java 应用程序服务器。nginx 在 443 上监听，而应用程序服务器在 8008 上监听。两者都使用 SSL 和相同的证书。Nginx 运行良好，但应用程序服务器很奇怪：

  • Postman 加载无错误
  • CURL 加载无错误
  • macOS 上的 Safari 加载时没有出现错误
  • macOS 上的 Chrome 可以加载页面，但 JavaScript 提取也会/openapi.json失败直接下载
  • macOS 上的 Firefox 失败（无法建立安全连接）
  • iOS 上的 Safari 失败

使用curl -v --http1.1 https://frascati.projectkeep.io:8008/openapi/表演：

为了比较，这里是 nginx 的输出相同内容：

我错过了什么？

答案1

正如对该问题的评论所指出的：

  1. 您的应用服务器正在使用 Java 8 JSSE，

  2. 它已TLSv1.3在可能的 TLS 协议中进行配置。

所述问题是由于缺乏对 TLSv1.3 的支持在 Java 的标准 SSLContext 实现中。因此：

  • curl建议TLS版本 1.3
  • 服务器接受，然后阻塞

评论：如果您使用的是 Tomcat，则底层本机库OpenSSLImplementation支持该功能。TLSv1.3
