Unable to access homeassistant.local:8123

Configuration
1

Upon rebooting my Home Assistant instance, I see that the UI on port 8123 doesn’t work. But the Observer URL on port 4357 seems to be fine. It says that all is fine on the Raspberry Pi.

I am also able to ping the IP address of the Pi from my Windows computer on the cmd and received replies.

Yesterday, I sort of played with my router’s settings to add a private Adguard Home DNS server. This Adguard is a standalone installation on another Pi. Both the HA Pi and the DNS Pi are connected to the same router through cables. I’m unsure as to whether that could’ve resulted in this mishap.

I can provide further details upon request. Please help.

Can you connect using the LAN IP instead, eg:

http://192.168.0.42:8123/

Nope that doesn’t work either. However, accessing the observer URL through 192.168.0.125:4357 works just fine. It’s just the GUI on 8123 that isn’t working.

Can you connect a keyboard and monitor, or SSH to it?

I’ve connected a monitor and keyboard to it. Trying to dig into the log files to see what I can find. But if you can tell me what exactly I need to look for, I would appreciate it.

Any and all logs really.

Start with HA’s own log, and then the Supervisor log, and anything else.

It’s really just a matter of looking to see what errors and warnings are logged.

This is the HA Core log

This is the HA Supervisor log

Am I right in guessing that the error in the core.py bool object has no attribute exit_code is blocking the GUI from loading on port 8123?

I also have four partial backups on the host. When I tried back restore <backup name>, the supervisor log shows an error saying that it is a partial backup and not a full backup. How do I get around this?

You’d need a full backup, if you have one you downloaded you should be able to upload it.
