title: getting 'internet not reachable' with sdkman
body: <p>Internet is working fine, but I'm getting this error from sdkman:</p>
  
  <pre><code>    06:47 $ sdk version
  ==== INTERNET NOT REACHABLE! ===============================
  
   Some functionality is disabled or only partially available.
   If this persists, please enable the offline mode:
  
     $ sdk offline
  
  ============================================================
  
  SDKMAN 4.0.35
  </code></pre>
  
  <p>My DNS does seem to be resolving very slowly. I can ping, but the resolution takes ~7 seconds. Could that be causing sdkman to time out?</p>
  
  <p>Any thoughts? what's the next step towards debugging? Thanks!</p>
