error listing snapshots - 400 Bad Request (500)

[lilodude]

Hello,

I recently had to reinstall my PVE and I am trying to restore my vm's and ct's. I've had the proxmox backup server connected to my PVE previously with no issues. However, after a fresh PVE install, I am getting the following error when attempting to access my backups:

PVE error:
error listing snapshots - 400 Bad Request (500)

PBS syslog:
Sep 11 12:59:27 pbs proxmox-backup-proxy[574]: GET /api2/json/admin/datastore/proxmoxbackup/snapshots?ns=root%40pam: 400 Bad Request: [client [::ffff:192.168.1.51]:34930] parameter verification failed - 'ns': value does not match the regex pattern
why does it seem like the backup server is being accessed over IPv6?

I'm able to ping the backup server from the PVE

I've updated both the PVE and PBS but I'm still getting this error. HELP please!

Hi,

PBS syslog:
Sep 11 12:59:27 pbs proxmox-backup-proxy[574]: GET /api2/json/admin/datastore/proxmoxbackup/snapshots?ns=root%40pam: 400 Bad Request: [client [::ffff:192.168.1.51]:34930] parameter verification failed - 'ns': value does not match the regex pattern

please share the storage configuration /etc/pve/storage.cfg on Proxmox VE. It seems the request uses the value root@pam for the namespace (ns) parameter, so likely a misconfiguration.

Hi,

please share the storage configuration /etc/pve/storage.cfg on Proxmox VE. It seems the request uses the value root@pam for the namespace (ns) parameter, so likely a misconfiguration.

Thanks for your help, here it is:

So i figured it out...I left the namespace blank, and I was able to connect with no issues.
