I have not changed config file since module 4 but Qbox server is refusing connection in module 5. Anyone facing same problem??
You’ll have to more specific with the error. Also, did you try going over Google for it?
For every new module, the old QBox directory along with the vsftpd binary and vsftpd.conf files will get removed and new files will be provided which should work without any changes from your side.
And please take some time out to think what could be going wrong before posting a query.
