Needed help: HA stopped working but is visible in the local network

Hi,

I’ve got a hassio installed on raspberry pi 2, everything worked fine until 2 days ago, I’m not able to connect to the UI, also other devices are unable to connect to the mqtt hosted as a plug-in (mosquitto). The strange thing is that I can see hassio in local network. I’ve connected raspberry using HDMI and took photo. It is looping the same lines over and over.

I would be grateful for any help.
