[SOLVED] PBS File Restore Broken

[linucksproxmox]

I'm attempting to do a file restore on a backup for one of my VMs, and I get this error message in a popup with no other context, not even whatever it's referring to "above."
Error: Starting VM failed. See output above for more information.

I tried from the shell and that gives some more insight:

# proxmox-file-restore list vm/104/2023-12-22T13:00:03Z /drive-scsi0.img.fidx --repository root@pam@192.168.1.16:8007:backup
qemu-system-x86_64: -drive file=pbs:repository=root@pam@192.168.1.16:8007:backup,,snapshot=vm/104/2023-12-22T13:00:03Z,,archive=drive-scsi0.img.fidx,read-only=on,if=none,id=drive0: PBS connect failed: command error: error trying to connect: error:0A000086:SSL routines:tls_post_process_server_certificate:certificate verify failed:../ssl/statem/statem_clnt.c:1889:
   
Error: Starting VM failed. See output above for more information.

I saw another thread that wound up with a different issue, and no solution: https://forum.proxmox.com/threads/file-restore-not-possible.109950/ and one more that sounds related https://forum.proxmox.com/threads/unable-to-run-backup-in-the-pbs-client.82407/ but I'm not sure.

I'm only running a single PVE host, and this command was run from the host. I verified I have ca-certificates installed, but not sure where to go from here.

UPDATE: Solved by rebooting the proxmox host which also runs PBS in an LXC container.

I hate to do this, but I want to bump this thread in hopes that someone can help with this issue. I asked on Reddit and it sounds like I'm not the only one with this issue, but so far I haven't found a solution: https://www.reddit.com/r/Proxmox/comments/18sa0j9/unable_to_do_file_restore_from_pbs_backup/
