TLS Invalid Token

I have the SEC_E_INVALID_TOKEN error coming up form the qtls_schannel.cpp (at line 1599 with MSVC) in every few days or weeks and kills my application with Q_UNREACHABLE:

        } else if (status == SEC_E_INVALID_TOKEN) {
            qCWarning(lcTlsBackendSchannel, "Got SEC_E_INVALID_TOKEN!");
            Q_UNREACHABLE(); // Happened once due to a bug, but shouldn't generally happen(?) 

I have to rebuild the whole qtbase if I want to change this to be non-fatal ?

I am using the TLS plugin through the QHttpServer with the Viber REST API.
