I have deployed SharePoint Hosted Apps on server and while trying to accessing it , it is asking credentials multiple times or continuously. I was entering correct credentials though was not able to access.
While searching on google I found DisableLoopbackCheck which helps me to resolve issue.
Detailed steps are as below:
Go To -> Start -> Run (Windows + R)
then Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
Right-click Lsa–> New–> DWORD Value
Type DisableLoopbackCheck, and then press ENTER.
Right Click On DisableLoopbackCheck and -> Modify
Change value form 0 to 1 and click on Ok.
Exit from Registry Editor and Restart PC/Server.
