Connection Problem

i cant connect to my ftp server, ther error im getting is this:

FEAT
500 FEAT not understood.

Hi, go to Tools->settings->connection and disable send feat.

hi, and thankyou so much for your prompt support.

I'm no longer getting the FEAT error, but it still wont connect for some reason.

"425 Can't build data connection: Connection refused"

Try to change on the same port with pasv or pasv with port.

pasv worked!
thankyou!!
