I recently moved from using HomeAssistant on VirtualBox on Windows to a dedicated server running proxmox. I created the VM using this tteckhelper script:
In July, I was just running a test to check if the HomeAssistant Backup feature would work and it worked fine, I could restore all the configuration and access my server.
However, I had to reinstall proxmox due to some hardware issues in the server that have now been fixed. I tried restoring that same backup (the very same backup file I downloaded in July, I checked the modification date) and after I initialize the new HomeAssistant instance and restore the backup, it wouldn’t allow me to connect anymore. When I try to access the HomeAssistant web page, it shows “Connection Refused”. I’ve checked the IP address is correct and it matches the one displayed in the HomeAssistant console. I also tested and if I shut down the VM, I instead get “Connection timeout”, which indicates the IP address is not wrong and the HomeAssistant instance is indeed there at that IP address but it simply replies RST to the TCP connection.
Since it worked in July but not late August, I thought version differences could be causing the problem. So I updated my old HomeAssistant instance (the one I’m backing up) to the latest version and re-did the backup, downloading a new backup file. When I restored the new backup file, the problem remained. I tried rolling back HomeAssistant Core to 2024.7.3 (which is the version I was running when I did the previous backup that was working) on both the old instance (the one being backed up) and the new instance. This produced the very same result: “Connection refused”. I tried rolling back HomeAssistant Operating system and got the very same result.
I’ve seen some posts recommending checking the HomeAssistant logs. I can see there are warnings and errors in the log but they are the same as in the old HomeAssistant instance. I’ve also seen other posts recommending to check the date on the new HomeAssistant instance. I also checked the date is correct.
I’ve created the VM on proxmox over 20 times over the course of more than one month on different days, but it always produced the very same error.
How can I restore my HomeAssistant configuration? Is there any way to fix this? Or perhaps another backup workaround that is more “manual” but might work, even if it doesn’t restore everything, it’s better than nothing.
