具有自定义域的 herokudns:没有这样的应用程序 [英] herokudns with custom domain: No such app

问题描述

我已多次查看

这些是我的 DNS 记录:

当我访问 omaiga.com.sv 或 www.omaiga.com 时，Heroku 回应:没有这样的应用程序.这里还没有."我做错了什么?

一些细节:

• 我可以使用 omaiga.herokuapp.com 而不是 protected-hookworm-0tshh2aii82icypukmovp7rz.herokudns.com 但我计划稍后实施 SSL，所以我需要让它工作使用 herokudns.
• namecheap.com 建议 用户将 301 重定向从我的根域重定向到我的www"，而不是使用 ALIAS 记录，以免影响电子邮件记录.

解决方案

我会回答我自己的问题:根据 Heroku 的文档 *.herokudns 地址不可浏览.相反，Heroku 使用来自客户端的Host"标头来确保正确的应用程序响应请求.

这里的问题是 Host 标头带有来自 Namecheap 的www"(因为我指定了我的规范名称 -CNAME-)，但我没有将www"提供给 Heroku，因此解决方案是添加Heroku 中带有www"的自定义域.

I've reviewed Heroku's custom domain tutorial several times but I can't seem to make my Heroku app work with a custom domain (hosted on namecheap.com). The problem: Herokudns doesn't resolve the app name

This is my configuration at Heroku:

And these are my DNS records:

When I go to either omaiga.com.sv or www.omaiga.com Heroku responds: "No such app. There's nothing here, yet." What am I doing wrong?

Some details:

• I could use omaiga.herokuapp.com instead of protected-hookworm-0tshh2aii82icypukmovp7rz.herokudns.com but I plan to implement SSL later so I need to make it work with herokudns.
• namecheap.com recommends to user a 301 redirect from my root domain to my 'www' instead of using an ALIAS record in order not to affect the email records.

解决方案

I'll answer my own question: according to Heroku's documentation the *.herokudns addresses are not browsable. Instead, Heroku uses the 'Host' header from the client to ensure the correct application responds to a request.

The problem here was that the Host header is coming with 'www' from Namecheap (since I made that my canonical name -CNAME-) but I didn't give the 'www' to Heroku so the solution is to add the custom domain in Heroku with 'www'.
