You can only add one additional server at a time. They should retry until the previous one finishes joining. Check the logs for progress.
If they never finish, check your etcd ports to make sure they can reach each other

The etcd ports reachable (tested with telnet). I hope I won't bother too much by providing a bit of info and logs, so thanks in advance... Here's what I did: I initialized the cluster on the first node (10.9.8.21), set up kube-vip in it with a virtual ip of 10.9.8.20 and tls-san for that address. Waited approximately 20 minutes and then tried to join the second node (10.9.8.23) which resulted in a failure. Here's the journalctl from both nodes:
Turns out that the second network interface (eth1) on each node was interfering despite setting the flannel iface to eth0 and node-ip… Once I recreated them up without the second interface and installed k3s there was no issue. Now I need to figure out how to make it work with both interfaces :)
