Can't add a new node to a cluster

[SagnikS]

Hi,
I have a cluster with 7 nodes, running for quite some time, smoothly. But on trying to add another node, it seems to fail, and I can no login to the 8th node using SSH (my SSH key was added, it asks me to provide a password, and the root password doesn't work either). Same for the Proxmox webinterface on the 8th node.
I'm using the GUI to add the node. I tried this 2 times, and I got the same issue. Any help would be greatly appreciated.

What happens if you try via CLI

pvecm add <ip-address>

Steps to verify
1. Login to 8th Node
2. Check you are able to ping all nodes via names and IP, check /etc/hosts file for relevant entry
3. do the following
pvecm add <ip address of the cluster master>

4. pvecm updatecerts

Thank you for your replies. It worked on the third try. I'll keep in mind if it happens again. Appreciate it!
