404 since update, how to recovery snapshots from SDcard?

I’m new to HA, installed two days ago on a PI, finally have all my integrations.

They was an update yesterday and since the reboot I have error 404 on the web interface

When I scan the port, it’s seems that 443/8123 is still open but nothing …

Tried to connected with telnet but was denied directly.

I did a backup yesterday on the PI but I didn’t downloaded locally

I mounted the HD card on a desktop, any idea where the configuration files and snapshots are?

Find the configuration in : PS found the configuration file inside hassos-data partition > supervisor > home assistant > tts

and the backup file seems to be in backup folder (parent folder)
