在域名到期后续订 SSL 证书，可通过 pf VPN 访问

Question

我是项目中的新 DevOps 工程师，SSL 证书已过期。 我们通过 vpn 访问此域 test.[smth].[smth].com，无法公开访问。 更新证书时出现错误。 这应该是由上述事实引起的。

  Certificate Name: test.[smth].[smth].com

尝试更新但不起作用。

连接超时（可能是防火墙问题）

如果您想在 LetsEncrypt 中使用 HTTP 质询来续订证书，则服务器需要可从互联网访问，并且还需要能够从服务器连接到互联网。 这似乎不是这里的情况。

如果您至少可以控制域的公共 DNS，那么您可以使用 DNS 质询 - 请参阅如何为非面向公众的服务器获取 Let's Encrypt 证书？ .
