Can't open attached files

Hello community of amazing people!
Sorry for my English, this is not my native language.
One kind of functionality of my application is that the employees of the organization contribute expenses for projects by filling out different categories and attaching a file (usually these are receipts in pdf format, but there may be pictures of different formats).
Everything worked fine, but literally yesterday almost half of the files became impossible to open using a link, this error appears.

Why did this happen? How to solve this? And how can this be prevented in the future?
Help, I really need your help!!
