A ta úžasná nová doména už má fungovat? Mně na ní Chrome ukazuje toto:
Your connection is not private
Attackers might be trying to steal your information from datovka.gov.cz (for example, passwords, messages, or c***t cards). Learn more about this warning
net::ERR_CERT_COMMON_NAME_INVALID
datovka.gov.cz normally uses encryption to protect your information. When Chrome tried to connect to datovka.gov.cz this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be datovka.gov.cz, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Chrome stopped the connection before any data was exchanged.
