Problem with php download when using my NAS

hello all:)
i have a fresh install of the latest version of nextcloud on a dédicated server. All wxorks fine, and it’s good:)

i have a little problem with the download fonction.

download fontion works fine when i use it directly, with the windows downloader or with some app like internet download manager,

but when i want to use it with my home NAS with pyload or synology download station, it’s don’t work…
it’s download only a php file like:

download.php?dir=%2FMedia%2FMovies&files=Monfilmdevacancessurlespingouinsenbaiedumontsaintmichel&downloadStartSecret=cb85698xxx4f1b

instead of my file “monfilmdevacancessurlespingouinsenbaiedumontsaintmichel.avi”

is a solution for this problem?

thanxs!!!

Nobody can’t help me… :(?
