2. Solution to FileZilla Server error 425 Can't open data connection for transfer of "/"

If "Use custom port range" is not set in the above settings

Then when the client connects to the server to read the directory, the following error will be reported: Response: 425 Can't open data connection for transfer of "/" Unable to obtain directory listing

This problem is mainly caused by using Passive Mode.

Solution: Check this option in the above settings window, set the port range, and add the port range to the inbound port in the subsequent firewall settings.

Special note: When using Alibaba Cloud server configuration, you need to add security rules in the server instance panel > security rules to set the Ftp inbound port to open.
