I am having a real issue with windows FTP server. We have it running in passive mode due to the firewall restrictions. Most of it works fine. People can connect, get and put files and list directories, but filezilla keeps failing to list one directory. I get the following:
Command: LIST Response: 125 Data connection already open; Transfer starting. Response: 226 Transfer complete. Error: Connection timed out Error: Failed to retrieve directory listing
The folder only has 59 files which is a total of 2.52MB all of XLS type.
I am completely at a lost as to why this is happening. If I delete half of the files it works again. Doing an experiment 49 files would work but 50 files won't. There are other folders with 300+ images which are full of jpg files of a larger size.
Is this a known Windows FTP server issue?
