title: Nuget 2.7: "an error occurred while processing this request"
body: <p>Since I while me and everbody in my team get this error message when we try to check for nuget package updates:</p>
  
  <blockquote>
    <p>An error occurred while processing this request.</p>
  </blockquote>
  
  <p>This only happens if I check in individual projects. It works if I do it on a solution level.</p>
  
  <p>I updated to nuget 2.7.40808.167</p>
  
  <blockquote>
    <p>Settings:<br>

  <p>I've already tried to deinstall and install it again. But nothing.<br>
  It also happens on my laptop at home (but with the same project).</p>
