title: Jekyll, Github pages + Custom domain failure
body: <p>I have just tried adding a custom domain to my Github page but now I have a message that says </p>
  
  <blockquote>
    <p>'404: There isn't a GitHub Pages site here.'</p>
  </blockquote>
  
  <p>If I build the page site locally all works as expected. So presumably I have not redirected the webpage correctly? How would I confirm this? I thought the problem may be the same as <a href="https://stackoverflow.com/questions/29099398/custom-domain-github-pages">this question</a> but I don't <em>think</em> it is, since removing or adding www does not change anything. </p>
  
  <p>I have not received any errors from Jekyll and have no clue where to look for what is going wrong. </p>
  
  <p>Any advice someone might have for fixing or identifying where to look would be greatly appreciated. </p>
  
  <p>The custom domain is <a href="http://sampassmore.com" rel="nofollow noreferrer">sampassmore.com</a> and the build of my website can be found <a href="https://github.com/SamPassmore/SamPassmore.github.io" rel="nofollow noreferrer">here</a></p>
