permission denied on Media backend files

Hello,
I have uploaded a file via upload button and converted the URL, so to be able to access it via browser or NPM request-promise module in backend.
It works OK and I am able to access the file when it is .jpg or .pdf , but when the file is .csv I get “permission denied” error.
Can you please help me why this error might be and how to arrange permission to uploaded .csv file ?
Thank you in advance !
