title: Unable to access raw.githubusercontent.com
body: <p>I want to download some files in github by raw.githubusercontent.com.</p>
  <p>When using golang to implement this function, I encountered the following error:</p>
  <pre><code>dial tcp: lookup raw.githubusercontent.com: getaddrinfow: The requested name is valid, but no data of the requested type was found.
  </code></pre>
  <p>My code:</p>
  <pre class="lang-golang prettyprint-override"><code>url1 := &quot;https://raw.githubusercontent.com/pupillord/tiny-cs/main/README.md&quot;
  
  // the error mentioned above will appear here
  resp, err := http.Get(url1)
  </code></pre>
  <p>Note:
  If I open it directly on the website, I can access the file normally.</p>
