Hello! I tried to make multiple connections to QNetworkAccessManager finished() signal.
I have ApiHandler class which makes a request handling.
And need to call a specific function after request finished (make use of slots).

I tried to make realization as below. But always worked only one connect (which is first one) - validateTokenFinished.
Explain how to properly realize what i want.
Thanks!
