Images without extension doesn't display

I am in the process of changing accommodation. The site I am in charge of is designed in VueJS / Nuxt and Laravel. Before, I was at CleverCloud and I try to go to OVH. Everything works except some of the images. It is not me who made the beginning of the site and I admit that I do not understand how it is possible ... There are many images (eg user avatars) which are saved in files WITHOUT extension and therefore in the database the avatar address is also without extension.

I haven't changed anything and at CleverCloud it works very well, the images are displayed well with a link like: (with a dot at the end)

https://site/storage/truc/image_600ab34a2e01d.

The storage folder is in the Laravel public folder. Except that at OVH, it sends me a 404 even though the file does exist! And when I have images with extension, for example:

https://site/storage/truc/image_600ab34a2e01d.jpg

It works without problem. So I deduce that the problem comes from "without extension" ?

The mystery is also why some are with and others without extension ... but at CleverCloud it works very well so I don't see why it doesn't work ...

How can I do on OVH ?

For example, that picture works : (it's in CleverCloud, the same doesn't work on OVH) https:// bopreprod. okgenie. fr/storage/wishes/image_60a6203e73cf7.

Thank you
