Site Collection cannot access by Site Administrator

Question

I am creating web application on port 80 with host header beta.xxx.com with DOMAIN\spadmin account with Allow Anonymous access. Then I create site collection. Everything goes correct.

Now when I try to access the website outside server on internet beta.xxx.com then it will ask for user password which I provide and website opens but when I try to access Site Settings it always ask for username and password never stops.

What can be the reason for it. !!!

You can try disabling loopback check as explained in the KB - https://support.microsoft.com/en-us/kb/896861

Method 1: Specify host names (Preferred method if NTLM authentication is desired)

To specify the host names that are mapped to the loopback address and can connect to Web sites on your computer, follow these steps:

5. Type BackConnectionHostNames, and then press ENTER.
