Windows authentication keeps asking username password even credentials are correct

I have developed an application to allow windows authentication and hosted it to the live server. in my local pc i am able to get the username password. but when i am accessing from web (e.g. websso.mydomain.com) it keeps asking credentials even after i entered correct credentials.

<authentication mode="Windows">
</authentication>

<authorization>
  <deny users="?" />
</authorization>
<identity impersonate="true"/>

i have added above tags in web.config, hosting server is windows server 2008 R2. I have tried to get username from 

WindowsIdentity.GetCurrent().Name
Environment.Username
Request.ServerVariables["LOGON_USER"]
Request.ServerVariables["AUTH_USER"]
HttpContext.Current.Request.LogonUserIdentity.Name

Is there any changes which needs to do in IIS or any steps to follow to configure windows authentication.

Installed IIS version is 7.5

websso.mydomain.com looks like internet domain name, not intranet domain name because it has sections. According to https://support.microsoft.com/en-us/help/258063/internet-explorer-may-prompt-you-for-a-password you should use domain name without sections (e.g. http://websso/) or add your domain name to security settings of client browsers

Try updating your <authorization> to include an <allow> element as I have done here.

E.g. 

<system.web>
    <authentication mode="Windows" />
    <authorization>
        <allow users="yourdomain\someotheruser" />
        <deny users="?" />
    </authorization>

I had a similar issue recently, try ensuring that the windows user has read access to the directory on the server.
