Why do SharePoint sites keep asking for login, 401 unauthorized error?


I am having issues with the SharePoint sites opening in Lenovo (till now checked on vibe, K3 note and A6000 plus).

Some time the site keeps on asking login credentials once supplied correctly.

In some sets it directly displays 401 unauthorized error.

Is there a setting which needs to be done here? 

tried Chrome and normal internet browser.



Hmm.. Can you check date, time, and time zone of your phones? Make sure they are correct. I notice that happening similar problem happening before when I change my time.
