title: Does android's DownloadManager automatically queue downloads for later even if they're from a local server, when network doesn't have internet?
body: <p>My application uses DownloadManager to pull files it needs from a local server (expressjs), and this works fine when the network has internet.  The actual use case is on an airgapped network, and it seems like DownloadManager never attempts to download the file in this situation (no cellular service, wifi only, wifi doesn't have internet).  In the airgapped situation that my application is failing to download, I'm able to use chrome on the device to navigate to the same url that DownloadManager uses and download the file successfully.  </p>
  
  <p>Is this a default behavior for DownloadManager, and if so, is there a way around it?  </p>
