Power failure killed my Hassio installation

I got a power failure and after this my Hassio will not work anymore:( I run it on a rasp and I can ping the ip, but I cannot SSH into the unit. When I connect a monitor to the rasp I see the nice HA logo but after like 10min the screen goes black…

I have some old snapshots but would like to get my config etc, is there any way I can take the SD card and browse the SD and find the config and DB files? Or do anyone know how to start my Hassio again?

Found this and it helped me:)
