Hi community, 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. ![](/sites/default/files/inline/images/2018-08-29_09_53_59-production_configuration.png)![](/sites/default/files/inline/images/2018-08-29_09_54_22-production_configuration.png) Any idea?
