Good afternoon, periodically during the day the connection to google.com, youtube.com, web.wharsapp.com is lost, an error occurs, the connection is not secure, NET::ERR_CERT_COMMON_NAME_INVALID. Sites are usually available in 15-20 minutes. I work as an IT specialist in a small office, 30-35 computers. And such errors appear on all computers. With what it can be connected?
