我按照此链接中的说明更改了我的 CNAME 记录 https://devcenter.heroku.com/articles/custom-domains .重定向本身有效，问题出在 Chrome 中(我假设其他浏览器)它给了我一个网络钓鱼警报。
This is probably not the site you are looking for!
You attempted to reach app.grewpr.com, but instead you actually reached a server i identifying itself as *.herokuapp.com. This may be caused by a misconfiguration on the server or by something more serious. An attacker on your network could be trying to get you to visit a fake (and potentially harmful) version of app.grewpr.com.
You should not proceed, especially if you have never seen this warning before for this site.
我将如何修复此错误？它还在 https 锁上放了一条红线。
最佳答案
由于您使用的是 HTTPS，您应该遵循稍微不同的 DNS 配置说明:https://devcenter.heroku.com/articles/ssl#configuredns
