Getting FTP to work?

This frustrates me because FTP works just fine on my first HA box…

I would like to use FileZilla to access some HA files. When I first tried it, it didn’t work. After some looking around, I added the FTP addon and double checked to make sure that the username/password in the add-on configuration and FileZilla match. However, when I try accessing the HA using FileZilla, I am greeted with:

|Status:|Connecting to 192.168.73.189:21…|
|Status:|Connection attempt failed with ECONNREFUSED - Connection refused by server.|
|Error:|Could not connect to server|

What am I doing wrong?
