This is the error message that you almost find when you use Filezilla:
Response: 200 PORT command successful. Consider using PASV.
Error: Connection timed out
Error: Failed to retrieve directory listing
I ran the Filezilla configuration wizard to diagnose the problem. The configuration wizard utility ran for a while reporting success until the very end. After timing out, I received the following messages:
Response: 200 PORT command successful
Response: 150 opening data connection
Response: 503 Failure of data connection.
Server sent invalid reply.
Searching the Internet led to not so helpful posts such as "Please read the Network Configuration guide.". After analyzing the situation, it turns out the solution isn't so obvious. My Client had the default setting of Connection -> FTP -> Active Mode: Get External IP Address From This URL. Which pointed to http://ip.filezilla-project.org/ip.php . This is the source of the problem. If you go to that URL, you will probably get a result of 127.0.0.1. If the Filezilla client needs the external address, and is given 127.0.0.1, then there will be problems indeed!
If you have a similar problem with Filezilla, and the problem persists even when the Windows Firewall is disabled, here is what you need to do
- Open Filezilla, go to Edit -> Settings
- Click on Connection -> FTP: Choose Active
- Click on Connection -> FTP -> Active Mode: Select "Ask your operating system for the external IP address”
- Click on Connection -> FTP -> Passive Mode: Choose Fall Back to Active Mode
- Press OK.
Try connecting to your FTP site once again. It will work!!
