Fixing broken cluster

Hi Community,

I have two small servers in my homelab: one at 192.168.1.100, the other at 192.168.110. I had a network issue and decided to set a static DHCP address for the second at 192.168.1.120. Unfortunately, this broke the cluster: the UI returns the error message "hostname lookup 'LAB-server5' failed - failed to get address info for: LAB-server5: Name or service not known (500)" and freezes. I then need to manually edit the cluster config file to update the IP address for the second server.

I've read that I could edit the corosync.conf file (https://pve.proxmox.com/wiki/Cluster_Manager#pvecm_edit_corosync_conf), but it seems I don't have the required privileges, although I SSHed as 'root'...

Can anyone tell me what's the appropriate procedure to modify this file? If this is the proper file of course...

Thanks in advance for any help!
