Failed Directory Listing

#1 Post by tmcasto » 2021-02-24 00:18

I've been using FileZilla for a long time. I recently got a newer computer and now FileZilla can't retrieve the directory listing. I've searched on here and online and tried a lot of things. Nothing has worked so far and I'm at a loss. To be fair, I don't know a lot about this stuff. I just need to be able to update my webpage. This is what the log says:

I've tried:
1. turning off the firewall

2. In FileZilla, click on “File” menu and choose “Site Manager”
Add the site or server you want to connect to if it’s not already in site manager.
Add hostname
change encryption to “only use plain FTP”
Change logon type "Normal"
Enter username/password.
Ok/Connect to continue

3. 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

4. Creating a Firewall Rule

When I try a second time after the first time failed it gives this message:

I'm lost and have no idea what to do. This is so complicated to me. I spent 5 hours yesterday and got no where. Please help.

Command: PASV
Response: 229 Extended Passive Mode Entered (|||50357|).
That's a broken server. It does not reply to PASV in the reply format mandated for PASV, it for some reason answers in the format reserved for EPSV.

Please contact your server administrator or server hosting provider for assistance to have the server fixed.


An alternative reason could be a very much broken firewall or NAT router that intentionally sabotages FTP by changing commands and replies.

Thanks for the reply! I have had the same server administrator and server hosting provider since 2006. So I'm guessing it's probably my firewall as that is what has changed. How do I fix the firewall? I tried turning it off completely and I still couldn't get the directory listing.

Well, I switched back to my old firewall program that was on my other computer and had a computer tech turn off all the firewalls. I still couldn't get the directory listing. So that rules out firewalls. We did switch from At&t internet to t-mobile internet. I wonder if that is the problem? Not sure how to check if that is the problem or how to fix it. Any ideas?

Mobile ISPs, they habitually sabotage data, such as degrading image quality or injecting ads into websites.

You need to do one of two things: 1) Demand your ISP from stopping data sabotage. 2) If that didn't fix it, sue them for breach of contract, they are not providing you with a working internet connection if they tamper with the data.
