Dears,
Kindly note that I have a website deployed on IIS 8 in windows server 2012.
When trying to access the website using the host name, the login popup appears and when entering the windows credential, I can enter to the website successfully,
When trying to access the website using the IP address, the login popup appears and when entering the windows credential I cannot log in, and the pop appears again, trying more it returns the same behavior when canceling the popup it gives me the below error:
HTTP Error 401.1 - Unauthorized
Please note that the "Anonymous Authentication" is enabled using the IUSR identity, and the Windows Authentication enabled with the NTLM and Negotiate providers and the NTLM is first.
I am trying to fix this issue by edit the registry value BackConnectionHostNames and DisableLoopbackCheck following steps in the below article from Microsoft

Thank you in advance
