The quality of the image inside your zip is low. It says it's a 3840x2160 image but the information is degraded. So i watch what is on the server.
- the first image you uploaded, that has a name that should end with 20230227222646 is the only good one. No error was logged for that image, and yet i don't see entry on the page (it could be worth a try to uploaded it as a single image). Compared to the one you uploaded 1 second after (so i guess as a group of files), there are other differences beyond quality: light is different, elements are misplaced (the image is slightly zoomed in) and copyright text at the bottom right is way bigger (different system ?)
