So when we call invalidateToken from slot connected to this signal and end up calling QNAM::clearAccessCache which waits on the thread for 5 seconds Backtraces: Qt HTTP thread: #0 0x00007ffff20c707f in pthread_cond_wait@@GLIBC_2.3.2 () #1 0x00007ffff43f0c0b in QWaitConditionPrivate::wait #2 QWaitCondition::wait #3 0x00007ffff43ea06b in QSemaphore::acquire #4 0x00007ffff45dcf6f in QMetaObject::activate [...] #9 0x00007ffff45dd607 in QMetaObject::activate #10 0x00007ffff4edbaf7 in QHttpNetworkReply::authenticationRequired #11 0x00007ffff4e0b2b4 in QHttpNetworkConnectionPrivate::handleAuthenticateChallenge #12 0x00007ffff4e10753 in QHttpNetworkConnectionChannel::handleStatus #13 0x00007ffff4e11cc9 in QHttpNetworkConnectionChannel::allDone #14 0x00007ffff4e14605 in QHttpProtocolHandler::_q_receiveReply Main Thread: #0 0x00007ffff20c7428 in pthread_cond_timedwait@@GLIBC_2.3.2 () #1 0x00007ffff43f0b56 in QWaitConditionPrivate::wait_relative (time=5000, this=0x136c580) #2 QWaitConditionPrivate::wait (time=5000, this=0x136c580) #3 QWaitCondition::wait (this=this@entry=0x136c788, mutex=mutex@entry=0x136c760, time=time@entry=5000) #4 0x00007ffff43efa6e in QThread::wait (this=<optimized out>, time=time@entry=5000) #5 0x00007ffff4e1edd3 in QNetworkAccessManagerPrivate::clearCache #6 0x00007ffff7b6fb03 in OCC::HttpCredentials::invalidateToken() #7 0x000000000057adb4 in OCC::AccountState::slotInvalidCredentials() #8 0x000000000057ac76 in OCC::AccountState::slotConnectionValidatorResult(OCC::ConnectionValidator::Status, QStringList const&) () #9 0x00000000005ab45c in OCC::AccountState::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) #10 0x00007ffff45dcd30 in QMetaObject::activate #11 0x00007ffff7b78671 in OCC::ConnectionValidator::connectionResult(OCC::ConnectionValidator::Status, QStringList) () #12 0x00007ffff7ae2514 in OCC::ConnectionValidator::reportResult(OCC::ConnectionValidator::Status) () #13 0x00007ffff7ae39b7 in OCC::ConnectionValidator::slotAuthFailed(QNetworkReply*) () #14 0x00007ffff7b784a9 in OCC::ConnectionValidator::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) () #15 0x00007ffff45dcd30 in QMetaObject::activate #16 0x00007ffff7b766dc in OCC::AbstractNetworkJob::networkError(QNetworkReply*) #17 0x00007ffff7af9f6e in OCC::AbstractNetworkJob::slotFinished() #18 0x00007ffff7b7654d in OCC::AbstractNetworkJob::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) () #20 0x00007ffff45dd607 in QMetaObject::activate #21 0x00007ffff4edd143 in QNetworkReply::finished #22 0x00007ffff4e3fec7 in QNetworkReplyHttpImplPrivate::finished #23 0x00007ffff4e41818 in QNetworkReplyHttpImpl::close #24 0x00007ffff7b7047b in OCC::HttpCredentials::slotAuthentication(QNetworkReply*, QAuthenticator*) () #25 0x00007ffff7b79092 in OCC::HttpCredentials::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) () #27 0x00007ffff45dd607 in QMetaObject::activate #28 0x00007ffff4e1d6fb in QNetworkAccessManager::authenticationRequired #29 0x00007ffff4e1ea07 in QNetworkAccessManagerPrivate::authenticationRequired #30 0x00007ffff4e3c784 in QNetworkReplyHttpImplPrivate::httpAuthenticationRequired Another case of Main Thread: #5 0x00007ffff4e1edd3 in QNetworkAccessManagerPrivate::clearCache #6 0x00007ffff7b6fb03 in OCC::HttpCredentials::invalidateToken() #7 0x000000000057b1e4 in OCC::AccountState::slotInvalidCredentials() () #8 0x00000000005abb8a in OCC::AccountState::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) () #9 0x00007ffff45dcd30 in QMetaObject::activate #10 0x00007ffff7b76ed5 in OCC::Account::invalidCredentials() () #11 0x00007ffff7ad55f5 in OCC::Account::handleInvalidCredentials() #12 0x00007ffff7afa69a in OCC::AbstractNetworkJob::slotFinished() #13 0x00007ffff7b7654d in OCC::AbstractNetworkJob::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) () #15 0x00007ffff45dd607 in QMetaObject::activate #16 0x00007ffff4edd143 in QNetworkReply::finished #17 0x00007ffff4e3fec7 in QNetworkReplyHttpImplPrivate::finished #18 0x00007ffff4e41818 in QNetworkReplyHttpImpl::close #19 0x00007ffff7b7047b in OCC::HttpCredentials::slotAuthentication(QNetworkReply*, QAuthenticator*) () #20 0x00007ffff7b79092 in OCC::HttpCredentials::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) () #22 0x00007ffff45dd607 in QMetaObject::activate #23 0x00007ffff4e1d6fb in QNetworkAccessManager::authenticationRequired
