现在问题发生在它说要更新我所做的 DNS 设置，但是我的应用程序与 https 的链接（“ https://tamuslide.org/ ”），页面无法访问服务器。我查了一些东西，但有些人说它可能需要 24 小时才能传播，但它确实对其他人有用。
我使用 NameCheap 作为我的域名托管服务商，但他们没有 ALIAS/ANAME。他们的DNS设置有什么问题吗？我的看起来像这样：
www.tamuslide.org CNAME www.tamuslide.org.herokudns.com
tamuslide.org CNAME tamuslide.org.herokudns.com
当我dig +noall +answer www.tamuslide.org在控制台中输入时，我得到：
