IP address 169.x.x.x means that you do not have a network connection.  I don't think it has anything to do with your certificate.  With IP address 169.x.x.x that means the connection is not getting far enough to even check the certificate.

Thank you Dave for your answer,
 Yes, i Know IP address 169 is automaticall adress APIPA
but the workstations with win10 and win 8 worked normally, so no problem in network

Sorry but IP address 169 by definition means there is a problem in the network, at least for that workstation.  As long as it shows IP address 169, it will not be able to connect to other computers on the local network because it won't be on the same network segment.

That doesn't make any sense so maybe I'm missing something.  Do your workstations have to 'authenticate' to the DHCP server to get an IP address?  This article doesn't make a lot of sense to me: https://support.microsoft.com/en-us/kb/3033929
