Network error

[MartinD]

Hi,
In Qt 5.7.1/MSVC32 I create one instance of QNetworkManager. Then I'm making several get request per minute. After several minutes/hours, I receive these errors:

QNetworkReply::NetworkError(UnknownNetworkError) // first, error is received from error signal of QNetworkReply
QIODevice::read (QDisabledNetworkReply): device not open // then I receive finished signal from QNetworkManager, but I receive this error on QNetworkReply readAll() method

Can you please advise?

Are you deleting the QNetworkReplys after use? it might be just too much cluttering

Yes, I call reply->deleteLater(); on finished() signal.

Hi,

I have a vague memory about a similar situation but I can't currently remember the exact sequence. In any case, if possible I'd test with the latest stable version of Qt to check whether it's still happening.
