Important: Even if the use of certificates
makes the risks involved in remote connections and
software installation considerably smaller, they

restricted lifetime. If "Expired certificate" or
"Certificate not valid yet" is shown, even if the
certificate should be valid, check that the current
date and time in your device are correct.
