download returns Error: "The operation couldn’t be completed. Software caused connection abort"

Any Idea what could cause this?

Same problem here!

When starting download file, send the app to background and open app again i get this error message.

This error only happens when using the flight test application or production mode! When I try to debug using the emulator, this error does not appear!

From my investigation:
This issue happens on iOS 12. The scenario is

• App fetches API in the background
• App changes the state to Background
• App changes state back to Frontground
• Issue raises.
  The reason is on iOS 12, the error code changed from -1005(ios 11) to 53 (ios 12) so the lib we use haven't handled that.

@tuanmai great work tracking down the problem! Do you know which native library exactly should be handling the error? Maybe we can fix the issue there.

Someone knows a library that works on background for ios?

I think RNFS can

I tried switching to RNFS once, but it cannot handle parallel downloads well and I experienced issues with very slow downloads overall.
