Hi All,
When I am executing below request using Forms web request control, it returns (401) Unauthorized. But when I try executing same using browser, it works !
Web Request :
But, verifying ULS logs shows this : 'Claims Windows Sign-In: Sending 401 for request **** because the user is not authenticated and resource requires authentication'.
This works absolutely fine in SP 2013. But after migrating to SP 2016, we are seeing this.
Thanks.
Hi Nagarjuna Ch,
It sounds like it may be a server related loopback issue. Have a look at this support article as it may assist you.
