更简洁地说，这应该能够更好地突出我所看到的问题：
$ openssl s_client -servername plex.tv -connect plex.tv:443 2>/dev/null </dev/null | openssl x509 -text| grep 'Subject:'

为什么访问 plex.tv 域时需要提供 banksalmanac.com 和 convox.site TLS 证书？此外，如果我使用 www 子域，我会得到正确的结果：
$ openssl s_client -servername www.plex.tv -connect www.plex.tv:443 2>/dev/null </dev/null | openssl x509 -text| grep 'Subject:'
Subject: C = US, ST = California, L = San Francisco, O = "Cloudflare, Inc.", CN = plex.tv
我的本地 ISP（Comcast）和 plex.tv 服务器（Cloudflare？AWS？）之间似乎发生了一些奇怪的事情。有人知道这里发生了什么吗？我会就此事直接联系 Plex 团队，但我显然无法访问他们的支持论坛来发布这个问题。
答案1
所以最后我关闭了路由器和电缆调制解调器的电源，似乎问题已经解决了。我不知道发生了什么，也不知道是什么原因造成的，但我只能把这归咎于康卡斯特的怪异行为……
