A week or so ago, my FTP upload action starting causing an error. The error is:
Data connection cannot be opened with this PROT setting.. The FTP Connection works fine, the change of directory on the server action works fine. this error occurs when I upload a ZIP file containing an .EXE.
The FTP server is on a shared web host. The hosting company have been “less” than helpful. They’ve just whitelisted my external IP address & suggested I use the ip address of the server instead of the ftp.domainname.co.uk. I get the impression they have no idea.
I can make the connection & upload files perfectly fine through FileZilla or WinFTP. I have no proxy server to negotiate.
Here’s my Connection settings.
The port number is specified as 21.
