    Come sospettavo, il problema è proprio nella connessione HTTPS:<br>
    "SSL handshake failed"<br>
    <br>
    Quindi, secondo me, o sul sistema su cui è in esecuzione QGIS Server
    i certificati di firma digitale degli enti che emettono i
    certificati SSL per il protocollo HTTPS mancano o non sono
    aggiornati, oppure il processo di QGIS Server non riesce ad
    modificare il file qgis-auth.db a causa di mancanza di permessi di
    scrittura.<br>
