title: Error "Failed connect to github.com"
body: <p>I am a beginner to start with git. I have created my account on github. I created a new repository. But I am not able to push or update changes in github using the terminal. I am running the following commands:</p>
  
  <pre><code>mkdir ~/TestApplication
  cd ~/TestApplication
  git init
  touch README
  git add README
  git commit -m 'first commit'
  git remote add origin https://github.com/vinayptl/TestApplication.git
  git push origin master
  </code></pre>
  
  <p>When I execute last command <code>git push origin master</code>, it freezes for some time and give following error:</p>
  
  <pre><code>error: Failed connect to github.com:443; Connection timed out while accessing 
  https://github.com/vinayptl/TestingApplication.git/info/refs
  
  fatal: HTTP request failed
  </code></pre>
  
  <p>I am working on Linux Platform. What could be the problem? I have seen some of the answers from SO but not able to resolve this issue.</p>
