KDSoapAuthentication generates same Nonce with every start of the program

[Micelium1]

I am using KDSoapAuthentication class with KDSoapClientInterface. And the problem I stumbled upon is the fact, that after I restart my application nonces are getting generated same. This leads to the fact, that the server actively rejecting my authentication and I need to wait full 15 minutes untill server forgets old nonces.

To clarify, within the one execution of my application it gives unique "random" nonce to each request but if I close app and run it again, it will generate same sequence of nonces from the beggining.

The code I using to link KDSoapAuthentication to requests is as folows:
m_mediaService.setEndPoint(QString("http://%1/onvif/media_service").arg(ipPortStr));
m_ptzService.setEndPoint(QString("http://%1/onvif/ptz_service").arg(ipPortStr));

m_auth.setUser(user);
m_auth.setPassword(pass);
m_auth.setUseWSUsernameToken(true);   // Включаем заголовки UsernameToken
m_auth.setUsePasswordDigest(true);    // Включаем PasswordDigest вместо чистого текста

m_mediaService.clientInterface()->setAuthentication(m_auth);
m_ptzService.clientInterface()->setAuthentication(m_auth); 

first application run

second application run after 6 minutes
