Same problem as OP on a new install.
agdsign's solution seems to be related to my problem, as I don't have '/etc/pve/local/pveproxy-ssl.pem' and '/etc/pve/local/pveproxy-ssl.key'
And when I try `pvecm updatecerts --force` I get:
(re)generate node files
generate new node certificate
unable to load Private Key
139638785887104:error:0909006C
EM routines:get_name:no start line:../crypto/pem/pem_lib.c:745:Expecting: ANY PRIVATE KEY
generating pve root certificate failed:
command 'faketime yesterday openssl req -batch -days 3650 -new -x509 -nodes -key /etc/pve/priv/pve-root-ca.key -out /etc/pve/pve-root-ca.pem -subj '/CN=Proxmox Virtual Environment/OU=01a3e634-1c09-4279-a89f-934b78ed93c8/O=PVE Cluster Manager CA/'' failed: exit code 1
So something is amiss here...
This is a brand new install. Haven't changed a thing.
Can this be repaired or is it easier to reinstall?
Thanks
