Hi we are currently experiencing error when accessing "Open with Explorer" in DocLib and davWWWRoot on our QA SharePoint 2013 Portal. After 3 log in attempt it show below error:

Message from webpage
We're having a problem opening this location in File Explorer. Add this web site to your Trusted Sites list and try again.

I already tried below items but nothing works:

  1. Re Create new SSL Certificate for https
  2. Installed SharePoint Server Foundation SP1
  3. Added the Site to trusted Sites List
  4. Start/Re Start and Re Install Web Client

Anyone experience this same issue?

Any help is appreciated.


  • does it works when: 1. access without https? 2. access from other pc?
