I am getting below error while accessing IIS website
HTTP/1.1 401 Unauthorized
Cache-Control: private
Content-Type: text/html; charset=utf-8
Server: Microsoft-IIS/10.0
WWW-Authenticate: Negotiate
WWW-Authenticate: NTLM
X-Powered-By: ASP.NET
X-Frame-Options: DENY

Content-Length: 5981
Proxy-Support: Session-Based-Authentication
HTTP Error 401.2 - Unauthorized
You are not authorized to view this page due to invalid authentication headers.
<fieldset>
Most likely causes:
- No authentication protocol (including anonymous) is selected in IIS.
- Only integrated authentication is enabled, and a client browser was used that does not support integrated authentication.
- Integrated authentication is enabled and the request was sent through a proxy that changed the authentication headers before they reach the Web server.
- The Web server is not configured for anonymous access and a required authorization header was not received.
- The "configuration/system.webServer/authorization" configuration section may be explicitly denying the user access.
</fieldset>
<fieldset>
Things you can try:
- Verify the authentication setting for the resource and then try requesting the resource using that authentication method.
- Verify that the client browser supports Integrated authentication.
- Verify that the request is not going through a proxy when Integrated authentication is used.
- Verify that the user is not explicitly denied access in the "configuration/system.webServer/authorization" configuration section.
- Create a tracing rule to track failed requests for this HTTP status code. For more information about creating a tracing rule for failed requests, click here.
