[PyQt] QNetworkAccessManager : server closed some connections prematurely

[iMath]

I made 24 requests to the network through QNetworkAccessManager::get() by a for-loop,after a few minutes later,the remote server closed some connections prematurely  before the entire reply was received and processed,then the queued/pending download tasks cannot be done,
so is there any anyway to allow me download all the files  these links direct to without letting the server closed some connections prematurely ?




here is the 24 request links(may be already expired)
