Restore on Rpi4 not working

Installation Home Assistant OS
1

Hi, I’ve moved from a Rpi3 to a Rpi4. Setting up the Rpi4 on Hass.os did work and I could access my UI and als install Add-ons. then I moved over my backup folder from the Rpi3 which also was running on Hass,.os and restored my latest backup.

After that, I was unable to access the Home Assistant Web UI.

When I try to start home assistant from the shell, I get also an error after a while;

core-ssh:/config# hassio ha start
Processing... Done.

Error: Unknown Error, see logs

Unfortunately I am stuck with troubleshooting. I did not find any issues in the /configuration/home-assistant.log. There are just two integrations that could not initialized (Tradfri, WeatherUnderground).

How can I troubleshoot the issue or is there any better way to migrate my HA to the new hardware?

All right, I’ve managed to fix this. For some reason my SSL configuration did not come over.

Afer commenting the SSL section in the configuration.yaml

http:
  # Secrets are defined in the file secrets.yaml
  api_password: !secret http_password
  # Uncomment this if you are using SSL/TLS, running in Docker container, etc.
  # base_url: example.duckdns.org:8123
  # base_url: https://hassio.rotters.com:8123
  # ssl_certificate: /ssl/fullchain.pem
  # ssl_key: /ssl/privkey.pem

logger:

my HA system came up again.

I have also recognized that the LetsEncrypt component was removed from my AddOns, so the system might have failed to generate a new pair of keys.

I hope this helps someone.
