  <p>I've this is from my laptop and I have a working connection to the feeds.  I did a little Wiresharking on the urls that are currently used and it looks like the location of the feeds may have changed?  I see this PR was submitted a couple of days ago:</p>
  
  <p><a href="https://github.com/jeremylong/DependencyCheck/pull/1172#pullrequestreview-108378384" rel="nofollow noreferrer">https://github.com/jeremylong/DependencyCheck/pull/1172#pullrequestreview-108378384</a></p>
  
  <p>I think this will resolve the problem but since builds are currently broken for me I'm going to try to find a workaround that will set the URLs that seem to have been moved without warning by NIST.</p>
  
  <p>Can anybody else confirm that they are having issues and provide an example of adjusting the location of the feeds on the command-line or in Maven?</p>
