FTP connection hangs

[Klaas Hobo]

When I connect to my server with filezilla I can easely upload a large amount of files by FTP. When I do the same in MC the system hangs when only 5% of the files is transferred. Are there some settings that I can to change in MC?
It stops at 256kb and 83 files so that's not a lot.

The error I get from the server is:
2015-10-27 20:51:39 > NOOP
2015-10-27 20:52:09 AntiIdle command NOOP Failed
2015-10-27 20:52:11 > NOOP
2015-10-27 20:52:12 < 425 Unable to build data connection: Connection timed out
2015-10-27 20:52:12 AntiIdle command NOOP Failed
2015-10-27 20:52:12 Connection have failed, Closing connection
2015-10-27 20:52:12 > QUIT
2015-10-27 20:52:12 < 200 NOOP command successful

What can I do?

Might be that your server do not support anti idle. you can try disable that.
Might also be a PASV/PORT issues. But since the "log" text you sent does not contain any logging for the transfer I cans say if it is that or not.
But looks like the server is closing the connection when NOOP (anitidle) is sent. some server do not like that.

Thanks for your reply,

The point is that I can easily connect and stay connected with Filezilla for a week and also transfer a ton of files. What information would be helpfull to give you a good direction?

Rgds,

Well then use the same FTP settings for AntiIdle and and PASV/PORT settings you use in Filezilla.

However, The problem is that most FTP server are unique and almost all of them are not following the standard FTP Protocol completely and some require additions and so on.  Dedicated FTP tools like filezilla have the time to add special workaround for different servers.
FTP in MC is more generic to give basic FTP support.
