Raspberry Pi3 b+ installing Hass.io problem

Hi all.
I just install hassio (hassos_rpi3-1.13.img)
and i have some problem when start Raspberry after installing image.
I can ping Raspberry ip (, but does not have access to port 8123 and UI
If i try use command like hassio > homeassistan info in hass.io cli (version 1.4.0) i get message The HTTP request failed with the error: Get http://hassio/homeassistant/info: dial tcp connect: connection refused
In host system (on raspberry) i can ping and can ping my home router
Does somebody have any ideas wich log i should check?

Problem was in NTP https://github.com/home-assistant/hassos/blob/dev/Documentation/configuration.md
