Bug: cannot see full documentation

When I try to see full documentation from UE4 editor all links redirected to https://udn.unrealengine.com/users/login.html, and I cannot login there with my actual credentials.

The UDN is reserved for Custom Licensee’s with the Unreal Engine. Can you post a screenshot of where in the editor you are being linked to that page?

Hi. I’d figured out how I got this problem.
I know what is cause of this bug.

  1. Several days ago I wanted to stop open UE Launcher when I begin to work with UE
  2. I had made PerforceBuild.txt empty file in "d:\Program Files\Epic Games\4.7\Engine\Build" folder (as it was suggested on answers hub). And launcher didnt appeared as I wanted. But happened problem with “full docs”
  3. I think Launcher linked with UE editor with some authorization flow. Because I revert all back: removed those .txt file, Launcher again start to launch and now I can see “full documents” site as before from UE Editor

Thanks for letting us know you were able to resolve the issue.
