title: VSTS Git-credentials not longer working for external tools?
body: <p>Since the last 3 days I experience problems when connecting with externals tools to Git repos on VSTS. I use GitKraken and I always had to generate Git-credentials in VSTS and the use them. Everything worked fine. </p>
  
  <p>In the last days now GitKraken started to prompt for login data again. Using the Git shell directly works without any problems. After trying several things (re-install GitKraken, reset Git-credentials in VSTS) I recognized that generating a personal access token (PAT) in VSTS solves this problem.</p>
  
  <p>I inspected the HTTPS traffic between GitKraken and VSTS and found responses with code <code>401</code> and the message <code>TF400813: Resource not available for anonymous access. Client authentication required.</code> when using my Git-credentials.</p>
  
  <p>Does anyone know if Git credentials are outdated or am I missing something here?</p>
  
  <p><strong>Edit</strong></p>
  
  <p>GitKraken will just show the login prompt again and again without giving me any error message.</p>
