Node.js Certbot-如何为IP:3030创建SSL证书和密钥？

我有一个仅在端口3030的IP地址上运行的ExpressJS应用程序

如何为此类地址创建SSL证书和密钥

我试过：

$certbot certonly--独立--电子邮件test1@yahoo.co.uk-d 127.0.1.1:3030

我得到这个错误：

请求的域127.0.1.1:3030不是FQDN

有什么想法吗

这是我使用的certbot

这是我的ExpressJS bin目录中的www文件：

#!/usr/bin/env node

问题是letsencrypt ssl证书是针对域名的，它与IP地址或端口没有多大关系。您必须拥有有效且可公开访问的域名，以便letsencrypt授权服务器可以对其进行验证

在这种情况下，通常的做法是在开发中使用http（而不是https），使用简单的检查，如：

if (process.env.NODE_ENV === "production") {
   // httpsServer.listen(httpsPort)
} else {
   // ...
}

根据和答案，可以在面向公众的ip地址上使用，但不能在保留的ip范围内使用，如127.0.0.0/24
