Hi,
i use a TSslFtpClient and TSslContext for upload and download data from
FtpServer over TLS.
some customers have this error:
500 Control connection closed - Connection aborted (#10053)
this is the section of code that i use for download:
FtpClient1.DisplayFileFlag := false;
FtpClient1.Passive := true;
FtpClient1.Binary := true;
if UseTLS then
begin
FtpClient1.SSLContext := CM.FtpCliSslContext;
FtpClient1.ProtLevel := 'P';
FtpClient1.PBSZSize := 0;
FtpClient1.SslType := sslTypeAuthTls;
end;
FtpClient1.ReceiveAsync;
anyone have a suggestion?
thank you in advantage.
this is the last part of ics log:
