I'm learning my way around PBS but now have this new issue that's appeared.
My instance is sandboxed and is using local PKI-installed certificates. Backups used to work, but now they don't.
The strange thing is that the first few containers backup OK and it fails when it gets to the first VM.
I've checked the fingerprint and that's OK. I can see the PBS datastores in PVE.

Slightly truncated log below.

Code:
