[SOLVED] Cluster authentification failure

[proxene]

Hello,

I will need help and fresh blood to solve my problem.

This is the first time I have this problem, usually everything works normally except when I want to add a new node to make a cluster I get this error :

Etablishing API connection with host '************'
The authenticity of host '************' can't be established.
X509 SHA256 key fingerprint is ************.
Are you sure you want to continue connecting (yes/no)? yes

401 401 authentication failure

I went through the forum and checked my actions on the wiki but without success. I already try to use -use_ssh and it doesn't work.

Can you help me ?

Thank you in advance.

Best regards,
Proxene

what command do you run?
you first have to do

pvecm create <clustername> [options]

and then from a second node to the one where you created the cluster

pvecm add <hostname/ip-of-node-already-in-cluster> [options]

Thank you for your reply

Yeah I already created a cluster on the 1th node.
I use this command on the 2th node : pvecm add *****

[dcsapak]

please upgrade your nodes so that both have the same version and try again
