Failed to download file from Complete FTP Server in .Net

Question

Hi, I have been using CompleteFTP server for a while and everything is working good.

Recently I used both free .Net component and .Net edtFTPnet/PRO to download file from the server. I can login and get modified dateTime of a file, but whenever trying to download a file I will get an exception.

I checked the error log in our server and found out it says

2013-07-15 16:48:55,788 ERROR [68952:"user email"] Failed to bind port 4564 on interface "ip address": Only one usage of each socket address (protocol/network address/port) is normally permitted
2013-07-15 16:48:55,788 ERROR [68952:"user email"] ServerException: Port 4564 is unavailable

Is it because I used exact port number in the server settings? I tried to download file from FileZilla and works good.

Can you help on this one?
Thanks!

Chris

Answer 1

It is best to enable logging at the Debug level in the server, and send us the zipped log file. Client logs at the highest possible log level would also be useful.

You can find support details here.

Answer 2

I found the problem. I have only set one port for the passive mode. I succeeded downloading the file in .Net using active mode.
