Lost access to home assistant web

Installation
1

Home assistant has been working find for me for quite a while. It’s running on proxmox and it’s on version 2026.1.1.

Last night, all the lights in the house turned off and when I checked HA on my mobile, it can’t connect. Tried to login on my laptop and it’s reporting “This page isn’t working - ERR_EMPTY_RESPONSE”. CLI through proxmox is accessible.

I’ve tried accessing via ip address as well as url with same result but the observer page is accessible and it’s reporting
supervisor: connected
support: supported
health: healthy
Also restarted the core in safe-mode + done a full restart and still can’t access the gui

What I have noticed in the CLI info is that the url is wrong
it was homa.goat-lovers.xxx and it’s changed to homa.goat-lovers.xxx.local

Core logs show an amber entry relating to a custom integratoin “hacs” which has not been tested
supervisor logs and host logs show no error.

Can anyone advise what I need to look at to try resolve the issue. I’d rather not rebuild if I can help it!

I haven’t had any problems, so I can’t be of much direct help, however others have reported something similar. You might want to review this thread

Right @ Goat-Lover
I assume you have good reason to have subdomain name for your HomeAssistant Server Name , in Your Home Network
Atleast it was good it changed it-self to .local

I use the IP address and it is working fine.
The mDNS / Avahi (*.local) stuff is about 40% reliable 90% of the time in 100% of the cases…

Due to some unconventional hardware/software within my network, I can’t use .local DNS zone for my internal services and use a split-horizons DNS setup instead.
I will go for a clean build as it now looks like a general problem based on the other threads I’m now seeing!
