in the last few days, my interned connection was “bumpy”… up, down, slow …
not sure if this is related, but as result my home assistant is not anymore reachable, while it is still fully working (at leas the ZigBee stuff…)
I have configured everything with the duckDNS add-on, hence LAN/WAN access is with an external URL
how can I investigate what happened? I can I access the web interface? shoudl I remove the firewall rules? how do I deactivate duckdns (so at least locally I can access)?
You can get access to HA by plugging in a keyboard and monitor directly to the host.
From there you can get a list of commands with ha help or edit your files. With ha addons you will be able to disable or remove your addons. I’m not sure if nano is preinstalled, but if it is, you can use nano FILENAME to edit files.
You could also try to access HOST_IP:4357 in order to access the observer
What do you mean by internal IP? You can access it inside your home network?
If that works I would double-check the settings of the router.
You could also try to ping a server outside of your network to ensure you have a basic internet connection. For example google which would be ping 8.8.8.8 in the cli.
Another thing to try would be to check the IP config in HA (Supervisor → system) against the IP config in your router. If you have configured a static IP and another device with that same IP, those two will fight each other
As you have UI access now, you can just go to config → Logs
Have you tried setting it to DHCP?
If you haven’t reserved the IP it could happen that HA will be reachable from another address. You would have to look that up in your router or reserve it before changing.
and see what I can do
