Lxc remote -> connection refused

LXD
1

I am trying to connect to a LXD remote from another machine. ufw is disabled. When I do: lxc remote add babylon 192.168.1.10:8443

I get this error:

Error: Get "https://192.168.1.10:8443": Unable to connect to: 192.168.1.10:8443 ([dial tcp 192.168.1.10:8443: connect: connection refused])

I run this on the server: lxc monitor --type=logging --pretty. Which gives me this output:

DEBUG  [2022-08-17T12:04:41Z] Heartbeat updating local raft members         members="[{{1 192.168.1.10:8443 voter} babylon}]"

sudo netstat -ltpn | grep lxd gives me this:

and curl 192.168.1.10:8443 gives me this:

curl: (7) Failed to connect to 192.168.1.10 port 8443 after 12 ms: Connection refused

lxc config show:

config:
  cluster.https_address: 192.168.1.10:8443
  core.https_address: 192.168.1.10:8443

I have no added IPTABLES rules.

But why I cannot get to add this remote?

Where are you trying to connect from?

I am connecting in the same network from a macos m1 machine.

Does curl 192.168.1.10:8443 connect when run from the LXD host itself?

You’ve most likely got a firewall setup without knowing it.

What does sudo nft list ruleset and sudo iptables-save show?

As always, you are right. firewalld had a couple of rules added, and I was not aware. iptable chains are a mystery to me.
