External connections do not work

[fuzzznet]

The problem

New installation of HAOS v12 on x64 mini PC. Everything works with local connections (Mosquitto broker, Zigbee2MQTT, File editor, Yeelight), but integrations and services associated with external connections (Meteorologisk institutt, Radio Browser, Ping (ICMP), Telegram, Traccar) do not work. External access from the Internet is open. The server URL is specified. The problem was identified immediately after installation; the standard integrations of Meteorologisk institutt and Radio Browser could not work. IPv4 - ON, IPv6 - OFF
