Management Point issue after upgrade to version 2002

Hi,

After upgrading from version 1910 to 2002, I faced an issue in MP only on primary site server (No issues on other MP servers):

MP Control Manager detected User Service is not responding to HTTP requests. The http error is 404.

Message ID: 5491

I tried to verify MP by accessing the below URL:

http://sccmserver.domain.com/sms_mp/.sms_aut?mplist

I received the following error:

Not Found

HTTP Error 404. The requested resource is not found

In addition I found the following on IIS bindings:

1- https with port 443

2- https with port 80

I think the problem with port 80 because the protocol type suppose to be http instead of https, I could delete it and create a new one with http and port 80 and stopped the error but after a while the settings is back to https and error occur again.

I'm not using SSL and no issue with other MP servers, last change I made was to upgrade from SCCM 1910 to 2002 after the update become a globally available for all customers.

So why this change occur on only one MP which is installed on the primary stand-alone site server?
