Since 31/01/22 all the download files become corrupted.
I own a Magento 1.9.4.2 store which has only downloadable products in it. Once a customer buy a digital product, Magento sends an email with the download link generated by Magento itself from the Dro...
I checked the http response header and it says:
content-disposition: attachment; filename="testfile.zip"
content-type: application/zip
but, as I wrote, once downloaded the file type become application/octet-stream and the file is corrupted. Any hints?
Here's the curl output from the Magento server:

Can you clarify what you mean when you say the file is corrupted? What is in the downloaded file? For example, is it empty, or missing data, longer than expected, etc?
Also, note that the "-I" option on curl only performs a HEAD request, meaning it only requests the headers, so it won't return the actual file data to inspect.
And it looks like the shared link you posted has been revoked/deleted. Do you have a current sample you can share?
Finally, note that the "dl" parameter is meant for use on "www.dropbox.com/s/...", not "dl.dropboxusercontent.com/s/...". You can find documentation for that here. You should use "www.dropbox.com/s/..." with that instead of accessing "dl.dropboxusercontent.com/s/..." directly.
Thanks for your reply. When I say the file is corrupted I mean the zip file you download cannot be extracted because "the archive is damage".
This some concrete example. This is a zip test file which contains a pdf. If I try to download the file from this url ( https://dl.dropboxusercontent.com/s/y33dnhk2rgquju4/testfile.zip?dl=1 ) from my browser I can extract it without any issue. If I try to do the same from my server it results corrupted.
This is the curl output from my server (check the wrong "content-type") [Result: Corrupted]:
