Issue

1. What problem do you get?无法下载https服务器的文件，文件服务器是私有的，证书也是私有的
2. Which version of FileDownloader are you using when you produce such problem?1.7.5
3. How to reproduce such problem?
4. Do you set FileDownloadLog.NEED_LOG=true?
5. Could you please reproduce this problem and provide all main process and :filedownloader process logcat
6. Can you fix it by yourself and request PR, if not, what's problem do you get when you try to fix it

P.S. If you don't know how to get :filedownloader process, it's recommended to using pidcat to just filter all your application logcat, or define process.non-separate=true on filedownloader.properties
