Portal Web Site Control Manager detected PORTALWEB is not responding to HTTP requests :Error on SCCM

Portal Web Site Control Manager detected PORTALWEB is not responding to HTTP requests.  The http status code and text is 401

Solution for this issue is check IIS services are running or not. If not start services. check the specified server is disabled in IIS or not. Check IIS binding. make sure IIS is configured to listen to same port on which SCCM site server is configured to communicate.either HTTP or HTTPS

mention IP Address of server while editing binding
