yandex: can't get snapshot url for device

Error message

yandex: can't get snapshot url for device: %s

What it means

Yandex GetSnapshotURL guard: the deviceID was not found among any household's devices returned by GetDevices (device id appended). Either the ID is wrong, the device is not shared with this account, or the devices list is stale.

Solutions

1. Verify the device ID matches one from GetDevices()
2. Confirm the Yandex account has access (sharing) to that camera
3. Refresh the session/devices list if it may be stale
