Connection error 596: ssl3_get_server_certificate: certificate verify failed

Hello,

I have problems on one of my cluster nodes.
I have Proxmox 4.4 cluster and I added a Proxmox 5 node to the cluster. When I added the node to the cluster I forgot to change the /etc/hosts file and I get several errors adding the node to the cluster. I correct /etc/hosts file and I managed to add the node to the cluster.
Now if I manage the cluster from another server that is not the new one and I click on a machine that is in it I get the following error:

Connection error 596: ssl3_get_server_certificate: certificate verify failed

The syslog of this servers says this:

May 31 18:39:31 pve10 pveproxy[22241]: Could not verify remote node certificate 'AA:79:0C:39:9F:EC:75:B9:41:E0:1D:F2:7B:F9:F0:9E:0A:1B:BA:97:8E:0E:32:FE:F4:6A:62:3D:AD:F6:C5:2A' with list of pinned certificates, refreshing cache

And if I manage the cluster from the new node it constantly ask me for user and password

The Proxmox 4.4 node pvecm status output:

root@pve10:~# pvecm status
