Recently trying to have 2 hosts to copy thought pve-zync i checked the keys seem to be fine so not sure if i need to delete the key?

root@prometheus4:~# pve-zsync create --source 109 --dest --  verbose --maxsnap 3 --name backupares
        ssh-copy-id -i /root/.ssh/id_rsa.pub root@
        /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ss                                                            h/id_rsa.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter                                                             out any that are already installed

/usr/bin/ssh-copy-id: ERROR: ssh: Could not resolve hostname Name                                                             or service not known
good god...i really need a vacation, was like 1 hour doing the same thing, but on because the servers are in a cluster i tried to replicate now i get this :(

2019-10-15 22:37:09 108-0: end replication job with error: hostname lookup 'prometheus4' failed - failed to get address info for: prometheus4: Name or service not known
Is 'prometheus4' a FQDN? As the error indicates, it can't find the domain name, you might want to try IP instead. If 'prometheus4' is correct, depending on you DNS setup, add A record for it or you could fallback to /etc/hosts on the machine you are replicating from.
thanks for the reply, yeah correct whats odd is that prometheus4 is inside of the cluster so not sure how it worked to connect to the cluster if it cannot find prometheus4, but i just did instead pve-zync thanks again
