Server Error in '/' Application. The Web application at [Domain name] could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content.

We are using SharePoint server 2013 Enterprise installed on windows server 2012 R2 Standard

This is the internet facing website with the following settings
-      Anonymous access enabled
-      Integrated Windows Authentication : NTLM
-      Authentication provider : Claim Based Authentication


When browsing the website publicly using the domain name I get the above mentioned Error, But if I login locally on the server [http://serverName/] then browse the website again using domain name the error disappears.



When browsing the website locally using the server name [http://serverName/]
1. I can access the website with no problems
2. And I am able to login into to SharePoint
3. When I browse a website locally on the server but using the domain name not the server name I cannot login into SharePoint it keeps displaying the authentication box as if I am entering the wrong credentials.


Below is the full error
