Unable to connect to homeassistant
This morning I saw all automation not active. So tried looking for problem. I can’t log in to my homeassistant
Sorry you have to type more context to your question.
I’t like saying that my car didn’t start today.
Hey, 
To have more context, first step: find out if the machine is still alive.
From a computer on the same network, run ping <IP of your HA box> (check your router’s DHCP list if you don’t know the IP). Then try both http://homeassistant.local:8123 and http://<IP>:8123 in a browser, not just the app.
- Ping fails → the host itself is down. Check power and LEDs; if it’s a Pi on an SD card, a dying card is the usual suspect. Plug in a monitor/keyboard to see the console.
- Ping OK but no web UI → HA crashed or the disk is full. SSH in if you can, or power-cycle it and watch the boot.
Also worth noting: your automations stopped working before you lost access, which points to the machine slowly failing (storage full or SD card wear) rather than a network issue. Tell us what hardware you’re running (Pi? NUC? VM?) and the ping result, and we can narrow it down.
No, it just means he realised there was an issue because automations were not working. Then, when he went to check, he realised that he couldn’t log in.
Looks like AI still hasn’t grasped cause & effect…
Problem solved…my machine was sleeping due to to cheapest price power socket that was turning off all my server rack devices connected to my ups.
I bought a power socket that was expensive 
. It does the job.
If it suddenly can’t connect, I’d first check whether Home Assistant is actually running and then try accessing it locally by IP instead of the hostname. If that works, it’s probably a DNS/network issue rather than Home Assistant itself.
