[CPP2255ALVIA]

I have a single node server after reboot the pve-cluster service doesn't work, also i get this error
root@ProxmoxCN:~# qm list
ipcc_send_rec[1] failed: Connection refused
ipcc_send_rec[2] failed: Connection refused
ipcc_send_rec[3] failed: Connection refused
Unable to load access control list: Connection refused

my etc/hosts file
root@ProxmoxCN:~# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
192.168.4.4 proxmoxCN.alvia.local proxmoxCN

# The following lines are desirable for IPv6 capable hosts

::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

root@ProxmoxCN:~# cat /etc/hostname
ProxmoxCN

i don't understand what's the problem.

hi,

* does the IP address of the node match with the entry in /etc/hosts file? (192.168.4.4)

* what do you get with hostname -i

 

[CPP2255ALVIA]

hi.

Yes, the IP it's correct I can access true ssh with it

root@ProxmoxCN:~# hostname -i
hostname: Name or service not known

 

[oguz]

what is the output from ip a?
