I don`t see that "it works". The file might have been downloaded ok, but the result is not right. The new version is somewhat better in that it tells you the "426 Data connection error". The file once again probably is present (downloaded) but now at least the response from the server is being looked at.
426 Data connection error
It is considered a transient negative reply as it is considered to be a temporary condition.
It is usually sent when the data connection is unexpectedly closed before the completion
of a data transfer.
In this case, the client is encouraged to restart the FTP transaction and try again.# GetFileSize("PRD80000000000000002587611", -1)

Response: 213 184 [2ms]The size is 184.

Status: Disposing(async) AsyncFtpClient.FtpSocketStream(data)We downloaded 184 and closed the connection. So phoooey.
Response: 426 Data connection error. [58ms]Looks like the server prefers to close the connection himself and calls that a failure.
The only reason that "worked" previously is because in the old version, for some reasons, such a negative response was not reported and not acted upon. Unclean and now fixed. Sadly that means this download is thus classified as failed.
We would rather need to concentrate what the Apache file server would prefer: Should we wait for him to close the connection when the download is finished? Ignore any error messages?
I realize that it worked before. But your log doesn't really show that. It shows cancellations, exceptions etc. I see no download success message. Of course the file might be present on the disk, but how safe is the assumption that all is ok. This apache server problem had been hiding behind the old versions code until it surfaced now.

Status: Closing/Disposing FtpSocketStream(control connection)On the FTP server, PRD80000000000000002587611 is a connection file ( size is 184byte ), The actual files are stored on another FTP server, and the file size >100G.

This FluentFTP version handles these things correctly. So it stops after 184 bytes. I explained that previously.
One way to handle this quickly is to provide a custom server handler and to provide
ServerHandler.AlwaysReadToEnd(...)Perhaps, we should introduce a new download FileExists option to allow saying "AlwaysReadToEnd".
