SCCM MPLIST MPCERT is not Working? I have seen a lot of MP issues where MPCERT and MP Policy tests are working fine. However, the MP list is giving errors.

Name resolution should work without any issues if you want a stable and reliable system. Check whether the DNS server is reachable or not.
MP List and MP Cert Test URL details
The following are the MP test details. This helps to understand whether the client is able to reach MP or not.
http://<ServerName>/sms_mp/.sms_aut?mplist
https://<ServerName>/sms_mp/.sms_aut?mplistwhere <ServerName> is the NetBIOS name for the MP Server.
Troubleshoot – SCCM MPLIST MPCERT is not Working
1) Try NSLOOKUP
nslookup
DNS request timed out.
The timeout was 2 seconds.
Default Server: UnKnown
Address:
> exit
(2)Try pinging the DNS server
ping
Ping request could not find a host. Please check the name and try again.
Refer to the valid DNS server and put the details in the DNS entry of the SCCM site server.
The best practice would be to keep more than one DNS server entry in the configuration.
