how did you solve this?
I think you would change the port and not the ip, right? (http://ip:59032)
I think you can change the port in /opt/tinycp/etc/tinycp.conf
Lxd is not native available at Debian. Only via snap raft.io.
So if you want to install und manage Lxd via tinycp, you have to go with Ubuntu and drop Debian.
