Can't connect on my new Mac

[ukcline]

I can connect perfectly to the FTP server on my old Macbook laptop, but on my new iMac with exactly the same settings, I get the following:

Status: Connection established, waiting for welcome message...
Status: Insecure server, it does not support FTP over TLS.
Status: Logged in
Status: Retrieving directory listing...
Command: PWD
Response: 257 "/" is the current directory
Command: TYPE I
Response: 200 Type set to I
Command: PASV
Response: 229 Extended Passive Mode Entered (|||64011|)
Command: PORT 192,168,1,88,225,17
Response: 200 PORT command successful
Command: MLSD
Response: 150 Opening BINARY mode data connection for MLSD
Response: 226 Transfer complete
Error: Connection timed out after 20 seconds of inactivity
Error: Failed to retrieve directory listing

Any ideas how I can get this to work? Oddly, it sometimes manages to connect - but rarely. Always works on the laptop, so clearly not a server issue - something with Filezilla.

That's the wrong reply to the PASV command. Either the FTP server you are using is broken, or some firewall or NAT router sitting somewhere between the client and the server is modifying the traffic.
