Notifications with images don’t work on LAN

Hello,

I experience a new problem.
Before, my automations was working absolutly fine.
I don't think i change anything related to this.
Here is my problem : i can't recieved notifications on my iOS compagnion devices when there is an image attached to it and when i'm on the local network of my HA, it's working fine when i'm in 4G, if there is no image it's working fine both local and internet.
I founded a solution, add "attachment: lazy: true" in my automations.

Thanks.
