📝 Description of issue:

Missing thumbnails in Places because request is for .mp4 instead of .webp proxy | 2024/05/17 21:24:05 [error] 29#29: *6815 open() "/protected_media/thumbnails_big/03c2e650f58ae866888fbe933a9443321.mp4" failed (2: No such file or directory)

A thumbnail with that name exists as .webp.

🔁 How can we reproduce it:

Probably: have a video in a distinct place. This would use the video thumbnail and it would create a request with the video's file extension instead of .webp
