I recently had to re-organize some files for a client using a Netgear ReadyNAs Pro 2, so I inherently reached for FileZilla to utilize FTP client for a speedy move, instead of the slow process of doing it via Windows Explorer on a Windows client.
However, although I had previously used FileZilla to manipulate files on this specific ReadyNAS device, this time around I could not connect and would get an ECONNREFUSED connection error.
After extensively searching the Internet, I could not get a reliable answer to fix this problem. Accordingly, I thought I would post what worked for me.......get ready for it........Restart the FTP service on the ReadyNAS!!!
I am not sure if it had anything to do with it, but since the last time I used FileZilla on this device, the device went through a firmware upgrade.
