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 Dropbox one. This is worked since 2013 from 31/01/22. Suddenly, it doesn’t work anymore. All the download files, past and present, become corrupted once downloaded!
The Magento web server is Apache and in front of it there’s a Nginx reverse proxy.
I also tried to restore my store from a 20/01/22 backup, but nothing’s changed. It still doesn’t work!
I checked the file types:
Downloaded from Magento link [Corrupted]: application/octet-stream; charset=binary
Downloaded from Dropbox link [Ok]: application/zip; charset=binary
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.
Here’s the curl output from the server itself:

If I this from my server it convert it to index.html then I have to manually mv index.html index.zip then unzip index.zip and it works.
