HA installation knackered

Hi

I would really appreciate a couple of ideas to try to fix a knackered HA.

I noticed no hot water this morning so I went to check HA in Chrome, but I couldn’t get on it, Chrome gave error:

This site can’t be reached
homeassistant.local refused to connect.

I tried to access via SSH but got access denied when entering password. I tried my normal username/password and also root with no password.

So I tried the current SD card into another raspberry pi and I got exactly the same issue so concluded issue is not the raspberry pi.

Decided to resort to backup which I have in Google Drive. I created a brand new HA installation via balenaEtcha, which gave me access to http://homeassistant.local:8123/. I selected restore from back up instead of new account on the onboarding page. However this produced the same result. I also tried an earlier backup and got the same thing.

It seem HA is half alive. Its on the network, I can ping it. And its also receiving MQTT messages (external MQTT node red is connected). However I can’t get to the main UI and I can’t access via SSH.

If anyone has any pointers, it would be greatly appreciated. It was working fine yesterday, only change I know of is the router did a reboot overnight. I always keep it up to date so its running the latest versions. Backup is only a day old.

Thanks in advance.

Look in your router for the IP address of your HA, and try http://IPADRESS

It make no difference if I use the IP address or hostname. I can see it on then network, I can ping it, but I can’t get to the main UI and I can’t access via SSH.

Connect a monitor and keyboard to the pi and check the console output and logs.

Yes I thought of that but I’d need to go and buy micro HDMI to HDMI cable, I don’t think I have one.

After nearly a whole day of buggering about with it, it has now suddenly sprung back into life! Happy its back but no idea what happened. I am pretty sure the SD card is screwed so no doubt that was part of the problem, but still can’t explain why the replacement SD wasn’t working, but now it is. Anyway thanks for the help!
