问题描述
虽然我有同样的问题，在这个，但我面临另一个问题，即，即使未在浏览器中运行，并显示此网页不可用，并且在我安装Heroku后发生。无法从终端访问github，甚至不能访问来自浏览器。
诊断后，我知道这个问题与我的WiFi有关，因为当我尝试打开在移动使用移动数据，它是开放的，但是当我连接我的手机到WiFi然后同样的问题，即这个网页是不可用的，当我在我的笔记本电脑上使用移动数据网络，但我可以访问该网站，但使用WiFi时此网页不可用。
我是运行Ubuntu（Linux），使用Windows-7进行双启动
诊断结果：

这绝对看起来像一个DNS问题，您可以访问网站通过IP但不通过URL。
您需要配置您的路由器DNS设置，我个人会将它们设置为Google的DNS服务器
8.8.8.8（primary）
8.8.4.4（secondary）
Though I have the same problem that is in this question, But I am facing another problem i.e, even https://github.com/ is not running in the browser and showing that this webpage is not available and this happens after I installed Heroku.
Cannot access github from terminal and not even from browser.
After diagnosis I get to know that this problem is related to my WiFi because when I try to open https://github.com/ in mobile using mobile data, It is opening but when I connect my mobile to WiFi then same problem i.e, this webpage is not available and when I use mobile data internet in my laptop I am able to access the site but when using WiFi this webpage is not available.
I am running Ubuntu(Linux), dual boot with Windows-7

This definately looks like a DNS issue, you can access sites via IP but not through the URL.
You need to configure your routers DNS settings, personally I would set them to Google's DNS servers
8.8.8.8 (primary)
8.8.4.4 (secondary)
