## Why this happens [#why-this-happens]

- The provider expired the long-lived credential Nordvec holds. Some providers
  do this on a fixed schedule, others after a period of inactivity.
- You changed your password at the provider, which commonly revokes all
  connected apps.
- You (or a workspace admin) revoked Nordvec's access from the provider's
  connected-apps or security settings.
- The provider rotated its security policy (for example after suspicious
  activity on your account) and invalidated existing grants.
