Db connection failed error when using passkey

[ilbarone87]

Since the update to latest version (v1.35.1) I've started to experience some random issues when using passkeys.

authentication works fine if user/pass is used.
My vaultwarden instance run on container and use NFS as backend storage (sqlite).
anyone else experiencing this?

use NFS as backend storage (sqlite).

Well, I would suspect that is the culprit.

turns out this was an ios client bug https://github.com/bitwarden/ios/releases/tag/v2026.1.0-bwpm

Purging trashed ciphers (or rather auth requests #6776) is not dependent on the client but is running automatically on a schedule, so the error message about failing to get the DB connection is likely not related to the iOS client but more likely related to you using NFS as storage backend for your sqlite database.
