Permission error after sync to new dataset

Hi,
I migrated from ixVolumes on truenas to datasets with this guide(https://docs.immich.app/install/truenas). But I have problem with videos.
Videos are "inacessable" and completely stopped working even downloading them is a problem. Problem is the videos are there but in log it says they are not there. Photos are completly fine and live photos too.

How can I fix this?
