title: Github pages custom domain showing a blank page
body: <p>I have a personal portfolio site hosted on GitHub pages. The address for this was: rpollock03.github.io/portfolio-site/</p>
  <p>I purchased a domain via Google robertpollock.dev</p>
  <p>I have followed Github's instructions to set this up, including enforcing HTTPS, but for some reason my site is still not loading.</p>
  <p>robertpollock.dev - the title of the page seems to load on the tab but the screen is otherwise blank.</p>
  <p><a href="http://www.robertpollock.dev" rel="nofollow noreferrer">www.robertpollock.dev</a> - safari can't open the page, can't establish a secure connection to the server.</p>
  <p>I have no idea what I'm doing wrong, but here is what I have so far. On Google Domain DNS settings:</p>
  <pre><code>Custom records 
  robertpollock.dev/A and www.robertpollock.dev/CNAME
  
  Manage custom records
  Host               name   Type    TTL        Data 
  robertpollock.dev   A    1 hour             185.199.108.153
                                              185.199.109.153
                                              185.199.110.153
                                              185.199.111.153
  www.robertpollock.dev   CNAME   1 hour      rpollock03.github.io.
  </code></pre>
  <p>When I use a DNS lookup tool this part seems ok:</p>
  <pre><code>Type    Domain Name IP Address  TTL
  A   robertpollock.dev   185.199.108.153
  Fastly (AS54113)    60 min
  A   robertpollock.dev   185.199.109.153
  Fastly (AS54113)    60 min
  A   robertpollock.dev   185.199.110.153
  Fastly (AS54113)    60 min
  A   robertpollock.dev   185.199.111.153
  Fastly (AS54113)    60 min
  Test    Result
      **DNS Record Published  DNS Record found**
  </code></pre>
  <p>Any ideas? Thanks!</p>
