TIC TCP Conn Errors in Ionic iOS real devices


I am using file transfer plugin to download images and text contents, for offline functionality. The app was working fine but nowadays the app is not working as earlier.

I debugged the app on a real device and got :

       iPhone <appname>(CFNetwork)[248] <Notice>: TIC TCP Conn Cancel [46:0x174396f40]
       iPhone <appname>(CFNetwork)[248] <Notice>: TIC TCP Conn Destroyed [46:0x174396f40]

this in the console.

The app stops downloading the contents and the progress bar gets stuck after this console error.

Do anyone have any idea how to proceed further to get the app downloading images and contents as earlier.

Any suggestion is appreciable.
