   I have the same issue on Android running Ionic. I have a podcast application that downloads episodes, and although most work well, some podcasts return a success, but have a file size of 0 bytes. Both links are downloadable in the browser though.
   
   Example of good URL: https://www.listennotes.com/e/p/54bb560d1a9e4ac1836662ee2c469030/
   
   Example of 0 byte issue: https://www.listennotes.com/e/p/8685f19b77874283a0b6e159eb7024ea/
   
   UPDATE - 31 Jan 2022
   
   I solved my issue on Android. I tested today on IOS, which worked fine, and since the above links work on a browser, I had a deeper look at Android. Both above links have redirects, which is handled fine by IOS. Turns out that Android java redirects using HttpURLConnection only work when the redirect protocol remains the same over each hop i.e. all http, or all https (by design, apparently for security reasons). In my case, the 'bad url' had multiple redirects, with a mix of protocols. So it stops when the protocol changes, and hence the file you download is the 302 redirect page where it changed, and hence you get a successful download, but with a file that is 0 bytes.
   
   My workaround is to add some code that manually follows the directs.
