When downloading a file from a secured area via HTTPS, the file download in Android Download Manager hangs. It displays that it would download the file and then do nothing.
Android 4.1.2 Jelly Bean
Default Browser (Chrome)
Interestingly, HTTPS downloads from other sites would work. So no general SSL issue. All the companies mobile phones are affected. It's not a phone problem. All downloads are affected. It's not the file. It works when using Firefox instead of Chrome. And it works with chrome on iOS.
It's the standard smartphone for several thousand employees. So installing firefox is not an option. Updates are not an option.
I first thought that the Download Manager would lose the session. So I put a debug proxy in between. The session information is passed correctly. The request looks good.

Even the response is exactly the same as the response that I get from a browser. With the debug proxy in between the server and the android smart phone, the download works. To me it looks like the difference is only the SSL certificate. When I use the debug proxy with SSL decrypt in the middle, the proxy uses the original ssl certificate. The android phone will get a certificate from the debug proxy.
Maybe there is a problem with certain certificates or certificate types?
