  • Hi everyone,

    we have a Problem with the online Status in the sccm console. in the bgbserver.log i found a lot of Errors like this:

    ERROR: Authentication failed - closing the connection. Exception: System.Security.Authentication.AuthenticationException: A call to SSPI failed, see inner exception. ---> System.ComponentModel.Win32Exception: The client and server cannot communicate, because they do not possess a common algorithm~~   --- End of inner exception stack trace ---~~   at System.Net.Security.SslState.StartSendAuthResetSignal(ProtocolToken message, AsyncProtocolRequest asyncRequest, Exception exception)~~   at System.Net.Security.SslState.CheckCompletionBeforeNextReceive(ProtocolToken message, AsyncProtocolRequest asyncRequest)~~   at System.Net.Security.SslState.ProcessReceivedBlob(Byte[] buffer, Int32 count, AsyncProtocolRequest asyncRequest)~~   at System.Net.Security.SslState.StartReceiveBlob(Byte[] buffer, AsyncProtocolRequest asyncRequest)~~   at System.Net.Security.SslState.ForceAuthentication(Boolean receiveFirst, Byte[] buffer, AsyncProtocolRequest asyncRequest)~~   at System.Net.Security.SslState.ProcessAuthentication(LazyAsyncResult lazyResult)~~   at Microsoft.ConfigurationManager.BgbServerChannel.BgbTcpListener.ProcessClient(Object state)  InnerException: The client and server cannot communicate, because they do not possess a common algorithm

  • Is there any error on site status

    \Monitoring\Overview\System Status\Site Status

    Also check the client logs for any errors

    CcmMessaging.log
    ClientLocation.log


    Also check bgpsetup.log and verify the component installed successfully

  • Do you have TLS 1.0 and 1.1 disabled in the environment?

    Is the Server OS fully updated with the latest CU?

    Are the managed clients fully up to date?

  • Hi,

    It looks like there are some issues with your certificate trust chain or verification of your SSL certificates.
    I suggest you try to check and make sure you have the latest updates installed for your ConfigMgr and OS, then you also need to check if the certificates are configured correctly.
    The following article lists the PKI certificates that you might require for ConfigMgr, I hope this is helpful to you:

    Best regards,
    Larry
