On a Mac, make sure the firewall is turned off in System Preferences > Security & Privacy > Firewall. If this fixes the problem, consult your firewall's documentation or support to learn how to allow FTP connections with the firewall turned on. The first thing we recommend is turning off any firewall software as a test. Turning on passive mode almost always fixes FTP connection problems. (Look for the words passive or PASV in the settings the checkbox is often labeled 'PASV FTP' or something similar.) Consult the documentation for your FTP program if you're unsure how to do it. If you use a different FTP program, it almost certainly has a checkbox to turn on 'passive mode' in either the connection setup screen or the program preferences screen. To solve these kinds of connection problems, turn on passive FTP transfer mode in your FTP program: Is there any other way to publish files?.It's also the problem if you see an error message mentioning a 'PORT' command. 'Passive mode' is especially likely to be the problem if your FTP program seems to connect to our server, but is then unable to transfer a file or show a list of files. (There may be other situations where it's needed, too - try the solution below even if you don't think you fall into any of these categories.)

If you use a personal firewall on your computer, or you're connecting from a company or ISP network that uses a firewall.

If you use some kind of Internet sharing device or software to connect multiple computers to the Internet using one ISP connection or.

The most common cause of FTP problems is that passive FTP transfer mode is not turned on in your FTP program. To see a more detailed answer customized for you, type your domain name here:
