eventlog analyzer error on add Vcenter 7.0

Hi guys
i have upgrade vsphere vcenter to 7.0 version 16189207
after upgrade event log analyzer cannot read log
and i try to delete it and add again
i deleted successfully
BUT when i want to add again and click to verify login, show  me error :
( Failed due to either wrong username and password (or) the server may be down! )
i used administrator@vsphere.loca user and i sure about password
and network connection is OK
eventlog analyzer version : 12050
how can i check log for add device OR add Vcenter LOG in evenlog analyzer?
