I use NSURLSessionDownloadTask to download the https file in the background, an error occurs with the error message:
Task .<17> finished with error [303] Error Domain=kCFErrorDomainCFNetwork Code=303 "(null)" UserInfo={_NSURLErrorFailingURLSessionTaskErrorKey=BackgroundDownloadTask .<17>, _kCFStreamErrorDomainKey=4, NSErrorPeerAddressKey={length = 16, bytes = 0x100201bb17485a920000000000000000}, _kCFStreamErrorCodeKey=-2201, _NSURLErrorRelatedURLSessionTaskErrorKey=(
"BackgroundDownloadTask .<17>",
"LocalDownloadTask .<17>"
)}
This error don't occur every time, but the probability is quite high, what is the cause of this error? Please help!
