[SOLVED] Certificates problem between pve and pbs

Jan 31, 2021
I had to renew a proxmox backup server running in one proxmox lxc. I used the exact ip as used before and backups of lxc and vm work fine.

If i try to backup the pve node comes a certificate error. It seems, the pve expects the certificate of the old pbs and runs in an error. How can i fix this?

root@pve:~# proxmox-backup-client backup root.pxar:/ --repository 192.xxx.xxx.xxx:pbsbackpPassword for "root@pam": ************Starting backup: host/pve/2021-04-15T12:23:04Z
Client name: pve
Starting backup protocol: Thu Apr 15 14:23:10 2021
Error: error trying to connect: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed:../ssl/statem/statem_clnt.c:1915:

Best regards
set the new fingerprint under 'datacenter -> storage -> your-pbs-storage -> edit'
Unfortunately i put the new fingerprint in there and the datastore is connectet. The issue occurs with the new fingerprint.

As i wrote, the pbs could be reached but the backup of root.pxar is not possible.
clear (or edit) /root/.config/proxmox-backup/fingerprints. we should probably fix this to display the stored and new fingerprint and print a meaningful warning at least..
