CLIENT HELLO 后 SSL 连接失败

Question

我在通过 https 连接到第 3 方网站时遇到一些问题，在 CLIENT HELLO 上连接失败，我很困惑为什么会发生这种情况。

具有讽刺意味的是，将笔记本电脑切换到备用互联网连接后，我能够正常连接到该网站，但在主要互联网连接上却失败了。这让我相信它不是笔记本电脑。 (不幸的是，永久切换到备份连接不是一个可行的解决方案)。

使用 tcpdump 我可以看到数据包来回传输，并且客户端重新传输了几次问候，但从未通过。使用 OpenSSL 进行故障排除，我得到以下输出。我尝试添加 -ssl3 和 -tls1 无济于事。有谁知道为什么会发生这种情况以及我该如何解决？
