MyFRITZ! Service

Message "Your connection is not private"

When you attempt to access the FRITZ!Box over the internet, your web browser displays one of the following messages:

  • "Your connection is not secure"
  • “This site is not secure”
  • "There is a problem with this website's security certificate"
  • "Cannot verify server identity"

Fig.: Chrome security alert "Your connection is not private"


  • The web browser describes the encrypted HTTPS connection to the FRITZ!Box as not secure or not private because your FRITZ!Box's individual security certificate is not known to third party organizations that validate certificates.
