As you probably have gathered from the logs, the server accepts the connection from the client, but then fails to send the initial welcome message, thus causing the client to time out after a minute. This is sometimes an indication that the port you have connected to is not an FTP server, but the fact that it works sometimes would indicate that it is. There really aren't any other clues in the log, so it's hard to guess what's going on. It seems pretty clear that it's a server error though. Are you able to inspect the server logs? Do other clients, such as FileZilla display the same behaviour?
