No Artwork on any Media player card with any media player tried

I have tried Arylic with Linkplay integration devices
I have tried Android TV Nova & Sony TV

I have tried with Mini Media player, Maxi media player & mushroom cards

No Artwork on any of it

The first check is if the media_player has the correct link, e.g.:

Ok I see this link. How do I see if its working?

That I donot know, the link allows the card to show the related media

I am using these (really) great cards
antontanderup/mediocre-hass-media-player-cards: Media Player Cards for Homeassistant.

Also my cards (no longer in day2-day use) ‘media-control’ and ‘mini media player’ show the picture each in their own ways.

That said, if you have the entity_picture with a link, then I can only guess it does not reach the source… tbh I have never seen this behavior before

EDIT: it should be locally retrievable, try this with the link from the attrib:
