title: Nexus marks every https proxy Maven repository as Unavailable and Untrusted Remote
body: <p>I have the latest version of Nexus installed and every time I add a new proxy repository that is <code>https</code> e.g. <a href="https://maven.atlassian.com/repository/public/" rel="nofollow">https://maven.atlassian.com/repository/public/</a> it marks it as <code>Remote Automatically Blocked and Unavailable</code> and <code>Untrusted Remote</code>. The problem is that it doesn't always work to re-specify the remote repository as <code>http</code> instead of <code>https</code>.</p>
  
  <p>How can I fix/troubleshoot this?</p>
