And here is more trace from my App:
I put some debugging log lines in the FTPClient_cs file and
FTPReply.cs file

It seems to hang as soon as it reaches the
ReadReply() function

by the way it's an UNIX WebSTAR FTP server. Not sure which version!

One thing to try - transfer in active mode rather than passive mode - that's what the command line client is doing.

Thanks for the help
making it an active transaction seems to have helped.

I'm still getting read errors but can now handle them better:
