Which QNetworkReply error for connection timeout ?

[Mixlu]

Hello,

I am trying to catch in a similar way connection timeout error when sending a request to a non-existing server between MinGW and WASM in the QNetworkAccessManager::finished signal.

Here are the results of the tests I have made (request to a non-existing server) :

With QNetworkAccessManager::setTransferTimeout(3000) :

MinGW : QNetworkReply::OperationCanceledError
WASM : QNetworkReply::ProtocolFailure

Without

MinGW : QNetworkReply::UnknownNetworkError
WASM : QNetworkReply::ContentNotFoundError

We can see that there is not a common error.

My question is, how could I differentiate a timeout error and a server who return an error ?

I am using Qt 5.15.2

I just saw that a QNetworkReply::TimeoutError code exists. Shouldn't this code be set when a timeout occurred ? Is this a bug or did I misunderstand something ?
