PROBLEMS WITH FTP -PASSIVEPORTRANG

Thanks for reaching out.

The error occurs because the current FTP script uses active mode, which requires the server to connect back to the client on random ports (e.g., 50214, 50215). These ports are blocked by the hosting provider. Since they only allow passive mode with ports 50000–50100, you need to switch your FTP client to passive mode.

Why Passive Mode Solves It

In passive mode, the server opens a port in its allowed range (50000–50100) and the client connects to it. This avoids firewall/NAT issues and the ‘425 Could not open data connection’ error.

Steps to Fix

1. Enable Passive Mode in Your FTP Client.
2. The built-in Windows ftp.exe does not support passive mode. Use a client that supports passive mode, such as WinSCP, curl, or lftp.

Example using curl in Passive Mode

Use the --ftp-pasv option with curl to enable passive mode:
curl --ftp-pasv -u "username:password" -T TESTFILE1.TXT ftp://test.com/DIRECTORY/
curl --ftp-pasv -u "username:password" -T TESTFILE2.TXT ftp://test.com/DIRECTORY/

Example using WinSCP Script

Create a script file (script.txt) with the following content: open ftp://username:
******@test.com/
option transfer binary
put TESTFILE1.TXT /DIRECTORY/
put TESTFILE2.TXT /DIRECTORY/
exit
Run it using: winscp.com /script=script.txt

Additional Notes

Passive mode ensures the server uses its allowed port range and avoids the ‘425 Could not open data connection’ error. If you need automation, WinSCP scripting or PowerShell can be used for batch transfers.

Let me know if the issue persists after following these steps. I’ll be happy to assist further if needed.
