For the last couple of days I have been trying to migrate my HA Core Docker installation to a new HAOS VM, on the same Proxmox host. I am also changing my domain name from a ddns.net domain to a co.uk domain on Cloudflare.
I got the new server up and running, then copied the config folder over from my Docker Core install.
I then managed to get a LetsEncrypt SSL certificate created using the LetsEncrypt add-in, and went on to try to configure Nginx Proxy Manager, as I have other websites on my original server which I wanted to preserve access to, using my ddns,net domain name.
Since then I’ve been having all sorts of issues with network connectivity. Last night I was completely unable to connect to the new HAOS console (I was getting ERR_EMPTY_RESPONSE errors). This morning that problem has mysteriously disappeared, but I am unable to open the Nginx Proxy Manager Web UI - the connection keeps timing out (it’s trying to access mynewdomain.co.uk:81).
I’ve also NEVER been able to access the new HAOS console using the expected URL’s (homeassistant.local:8123 or local.ip.address:8123) - I could only access it using homeassistant:8123 or mydomain.co.uk:8123.
I also noticed that the odd reference to my old ddns.net domain name in the new setup - for example I have automations which play media in the /local/www folder, and according to the HA log it is searching for that media in http://myolddomain.ddns.net/config.
This all looks like a bit of a mess, so I figure that maybe I should trash the new HAOS VM and start again. Can anyone advise on the best procedure for migrating from Docker HA Core to HAOS on Proxmox, while also changing the domain name. Any tips on how to handle the SSL certs would also be welcome, as I have now generated these for the new domain on my HAOS server.
Can anyone provide some guidance?
