make sure your vsftpd.log file capturing the logs of connection and transfer of files between local client and server by printing in CLI using cat command

yes i have checked it is capturing all the logs.

may be then you have not reestablished connection between your local client and QBox_server and then check log file is capturing this connection establishment and then try to reconnect with server
