Possible Solutions



You can receive that 421 error if the FTP server you are connected to limitations the total number of connections available or limits the connections available to one user. There are three things you can do:



1.

Limit the number of connections to any one FTP site by select Tools > Global Options > Connection and set "Per site max connections /transfers" to 1 (By default it will be set to 2).

2.

Remove items from the Transfer Queue. The Transfer Queue is where on earth you see items ready for verbs, in transit, or a short time ago transferred. Sometimes the Queue Pane can become cluttered with imperfect transfers. To clear the queue, right-click inside it and choose Remove All.

3.

Make sure only one instance of CuteFTP is running on your system. Open the Windows Task Manager and see if CuteFTP is programmed more than once.
