Hi,
Thank you for posting in Microsoft Q&A forum.
1,Please check if your certificates are well. You can open certmgr.msc on a client and check if there's any obvious errors there? Like an expired certificate or a missing/untrusted root certificate. Also review the site status and component status nodes in the Monitoring workspace in the console.
2,How many clients are facing this issue? Please help make sure that there is no firewall or anti-virus to stop the communication between the client and the MPs. Use the following URL to verify that a client can access the management point and the management point certificate information:
http(s)://<ServerName>/sms_mp/.sms_aut?mplist
http(s)://<ServerName>/sms_mp/.sms_aut?mpcert
Where <ServerName> is the NetBIOS/FQDN for the management point computer.
3,Please set the client connections to: Allow intranet and internet connections on the General page of management points' properties to have a try.
