Every time I try to add a trusted server on my gateway it log me out the gateway,
in the console I found the below error every time I click on "ADD" button which saves the trusted servers:

The error:
GET http://win-i6h7dc9igfa:8080/gateway/v2/apps/insight?otagtoken=1e8779a6-563c-41f5-a83f-91857ed29cee&cstoken=null&_=1417186110288 401 (Unauthorized)
I can see that I am not authorized to access something but I didn't know why or what is the problem with this action, knowing that if I enter a trash value to the "Backend Name" field in the trusted server's page it will be saved successfully.
so am I not authenticated to add CS as trusted server as done in below article ?

or the gateway is not authorized to access to the CS ?
or it is a tempobox / pulse module issue ?
or there is another thing causing this issue ?
Software used :
-CS 10.5.0 x64 update 2014-03 (tempobox & pulse are installed).
-APPWORKS gateway 1.1.6
-OS 7 x64 (VM).
