I've created a BS that uses FTP InboundAdapter. It works, read the file and process it.
The problem is when there not any file in the FTP folder, it raises the following error:
ERROR <Ens>ErrFTPListFailed: FTP: error en List para *.csv (mensaje='No-transfer-time exceeded. Closing control connection.',código=421)
I think it is something about the configuration, but I don't find what is the problem.
