ERR_CONNECTION_REFUSED after Restart due to power outage

Hey everyone,

Recently, there was a power outage at my house, which caused Hass.IO (Running on Raspberry PI 3, Version is currently unknown (sorry)) to restart. Since then, I can’t access the web UI, whether by “IP.Ad.re.ss:8123” or “hassio.local:8123”. Everytime it says “ERR_CONNECTION_REFUSED”.
I already tried accessing the cinfuguration.yaml according to (´THIS) topic, but even that wasn’t possible. Unfortunately, I also don’t have SSH or SAMBA set up, so nothing to do in this direction.

Here is the last Log and my configuration.yaml(*** means I blanked out this Information for privacy or security reasons). I retrieved both of them by taking the SD Card out, and accessing it within a Windows 10 Machine.

CONFIGURATION.YAML:

HOME_ASSISTANT.LOG:
Unfortunately, this is a 8.3MB File, which caused big problems, when I tried to paste it’s contents so instead, here is a link to the file: https://filehorst.de/d/dgvgjenw

Thanks in advance,
