SCCM client on primary site server

[si124]

I installed SCCM client on primary site server, but it does request policy from MP.

I allow only HTTPS protocol between clients and MP.

 

Certificate on SCCM Site server is OK.

If I look at logs on Site Server (c:\program files\sms_ccm\logs) i get this strange things:

SMSID 'eb435f1b-c21a-49af-a44b-061f9ff2edac' is invalid. ClientIDManagerStartup

No reply message from Server. Server may be temporarily down or a transient network error. CcmMessaging

Post to https://xxx/ccm_system/request failed with 0x8000000a. CcmMessaging

CRequestResponse::Send failed with code 0x87d00215 CcmMessaging

 

I tried to delete SCCM site server from devices, get it again from Active Directory discovery.

Uninstall client, install client manually. All without success.

 

SCCM Clients work on all other clients/servers without problems.

 

Thank you for your help in advance!
