COLD WAR problem

cant connect to online services cause severs may be undergoing maintenance, or you may be experiencing a network interruption. Please try again later. ive connected the activision account to, ive scanned and repaired, ive put everything to run as admin and still the same error anyone know whats up with it or how to fix it ??

You have had a network interruption just try again and if that doesn’t work then try using an ethernet connection
