Although this is aimed at Filezilla clients, the principles will work for any other FTP client as well.

FTP Symptoms

You enter all the detail from Host Africa, click on “connect” and ……. connection is successful, but no file listing appears or you get an error “Failed to retrieve directory listing”

FTP Transfer

Why ?

Lets have a quick look at the FTP protocol. In the early days of file transfer, IP addresses where plentiful and the internet was a trusting place. Your server could be easily accessed and the clients where on public IP addresses, thus connection was a straightforward one to one session. 

Then came the internet of data theft, viruses and malware. Hence the rise of firewalls. IP addresses where also getting scarcer and users more plentiful. 

Now we had to put multiple users behind NAT (Network Address Translation) firewalls. FTP stopped working in it’s default “ACTIVE” or one-to-one mode. 

Thus the ftp PASV or PASSIVE mode came into more common use. This mode enabled FTP connections to be established through a firewall by letting the client dictate the connection and opening extra ports for the data streams. 


Back to our problem and the solution

Most FTP clients default to “ACTIVE” mode and this connects fine, but fails when the server tries to send us data back. Thus we have to change to PASSIVE(PASV) mode to enable the data to reach our client.

This setting is found in the “Site Manager” menu of Filezilla under “Transfer settings.

Site Manager


Change the mode to “Passive” and click “OK” to save.

The other setting which could affect your connectivity is the encryption method.

There are four encryption method options in Filezilla. Choose each one in turn, click OK and connect to see if it works.

FTP TLS or SSL

One of these modes will usually work. Always try from top to bottom as we always try for the encrypted connections first to be more secure.

FTP is a wonderful tool for moving data to and from the internet and once it works, it works very well. At Host Africa we also provide FTP space as an “Addon” to any of our hosting packages at a very reasonable rate per GB.

Also, make sure that you have a good idea of the size of data you have stored as most service providers will assign you a certain data “quota” ie 10GB or 20GB, etc depending on what you are paying for. Once you have filled the quota, you could find new uploads merely failing as some ftp servers and/or clients are not very good at giving explicit errors.
