title: Eclipse Photon - Eclipse Marketplace not launching
body: <p>I just installed Eclipse Photon. I migraded one project from Oxygen to it - everything is working fine.</p>
  
  <p>The problem I noticed is that I cannot open the Eclipse Marketplace. Whenever I click on it, I get the loading circle for 1-2 seconds then nothing happens.</p>
  
  <p>I also tried this on a completely new empty workspace (so no old .metadata) - same behavior.
  I also restarted PC - didn't help.</p>
  
  <p>Any ideas? Is it me only that has this problem or is it a bug due to the new version?</p>
  
  <p>Thanks.</p>
