Can’t connect to homeassistant after restart

Hi… I use Home Assistant on ASUS THINKER.
There was a power outage yesterday and it is no longer accessible over web.
ping successful, ssh unreachable
I tried to connect the screen to asus tinker but there is no picture. I don’t know if it should be, I’ve never tried.
Also the API doesn’t work
How can I start the system?
If I fail, is it possible to copy the settings from the SD card to a new one with the new system?
Thankyou for help !!

Regards Rudi

nobody knows anything about it ??
