Getting 404 error from lovelace homepage - how do I recover?

Configuration
1

I’m running 0.117.5 on HassOS on a Pi4. Everything has been running well for ages, but this morning, I’m getting 404 errors when I go to port 8123 on the Pi. My automations are still working, but I have no control.

I can ssh into the OS and ha core logs shows nothing.
ha supervisor logs shows

Ideas?

Do you use node-red? I read about a similar error when updating node-red in one of the latest versions.

Not on this instance. The only addons are mqtt and openzwave .

Verify your config is correct. Specifically the section for authentication.

check ip is not banned

Try login from different device both from web and LAN

Clear browser cache and try login again

Unfortunately, as the front end is not available and HA is running on HassOS, I have no way to check the configuration. ha core config comes back OK, but I can’t see the individual files.

The same goes for the ip address. I’ve tried different devices. There is no WAN access for this instance.

SSH?

Pull sd card out. Stick it in PC. Check it.??

Could do, but it’s a pain.

(I’ve now moved HA to a VM)
