problem logging in to my website host's FTP site

[Jaimie]

Never had any problem using any FTP program to access my website until I moved to TENN and use Spectrum. Everything was fine with ATT but not available here...
Suddenly all my FTP programs will no longer access my website for uploading/downloading (FTP Explorer in Vista, FileZilla in Ubuntu, etc.). Seems to get logged in but at loading directory it times out getting this:

Connecting to XX.XXX.XX.X:21...
Status: Connection established, waiting for welcome message...
Status: Plain FTP is insecure. Please switch to FTP over TLS.
Status: Logged in
Status: Retrieving directory listing of "/"...
Command: CWD /
Response: 250 CWD command successful
Command: PWD
Response: 257 "/" is the current directory
Command: TYPE I
Response: 200 Type set to I
Command: PASV
Response: 227 Entering Passive Mode (XX,XXX,XX,X,XXX,XXX)
Command: MLSD
Error: Connection timed out after 30 seconds of inactivity
Error: Failed to retrieve directory listing
Status: Disconnected from server

Had similar problem with my amateur radio program Echolink (used to access local repeater near home when I'm on the road via internet), and the Echolink support pointed out according to their logs that my problem was with "port address translation" and suggested switching to using their proxy option:

showing that something along the path is doing port
address translation (PAT), which is not directly compatible with EchoLink.
Sometimes this is a characteristic of the ISP itself.
I recommend that you enable the Proxy option. Under Tools->Setup, click the
Proxy tab and choose Automatic Proxy Selection.

...but, I don't know how to do anything like this with FileZilla ~ really stupid when it comes to the proxy stuff. May not even be the issue... attached info displayed in DEBUG mode FileZillaDEBUG.txt
