Strange, was it possible to post a common FTP log as well? With method ReceiveAsync the component doesn't try to establish a secure data channel/connection. However some server may require it, just a guess (haven't read your attached log yet). If so, do not use method ReceiveAsync but the low level methods instead. Example FTP log, method ReceiveAsync, data channel plain text allowed: Executing Requested Command < 220 FileZilla Server version 0.9.24 beta Session Connected, error = 0 > AUTH SSL < 234 Using authentication type SSL !
