title: Must be a top private domain
body: <p>I'm learning about <a href="https://developers.google.com/identity/protocols/OpenIDConnect" rel="noreferrer">Google OAuth</a>, and it says that my  project has no appropriate credentials. </p>
  
  <p>So I go to the Developers Console and click on the <a href="https://console.developers.google.com/apis/credentials/consent" rel="noreferrer">OAuth consent screen</a>. I type my domain name into their question:</p>
  
  <blockquote>
    <p>Authorized domains  To protect you and your users, Google only allows
    applications that authenticate using OAuth to use Authorized Domains.
    Your applications' links must be hosted on Authorized Domains.</p>
  </blockquote>
  
  <p>I have verified my domain, but I get "Must be a <a href="https://github.com/google/guava/wiki/InternetDomainNameExplained#public-suffixes-and-private-domains" rel="noreferrer">top private domain</a>." The link takes me to some kind of java programming statement. Actually if I click on the Domain verification tab (again) there are no domain names listed, but I know I added it.</p>
  
  <p>Q: How do I add my domain for being used with OAuth? Must I qualify it as a Top Private Domain or am I going down a rabbit hole?</p>
