This is an example output from FileZilla, when the error occurs Befehl: LIST Antwort: 150 Opening BINARY mode data connection for file list Fehler: Zeitüberschreitung der Verbindung Fehler: Verzeichnisinhalt konnte nicht empfangen werden We can reproduce this behaviour with different Windows workstations using FileZilla V.3.8.0 . One workstation did not get such errors using FileZilla V.3.7.4.1. After an update to the latest version, this pc also get these errors. We also examined, that neither our firewall nor our FTP servers are responsible for this behaviour. A traffic capture shows, that the server answers the request and the workstation receives this answer. Then the connection is closed with FIN, ACK from from the server and ACK from the workstation. We can provide such a dump, if it is necessary." Bug report new normal FileZilla Client Windows XP & 7
