SFTP "Channel has been closed"

I am successfully using SFTP to get files from one site; however, I get an error message of "Channel has been closed" when the same program uses SFTP to a different location.

I suspect the second location is not defined for SFTP. Would that generate the message "The Channel has been closed"? If not, what would cause this message? The administrator of the second location is not a dedicated IT person so if I have specific questions for him, he can obtain answers for me.

I would appreciate your insight on this error message. Thanks!

Try disabling ZLIB compression as described in the SFTP tutorial (no need to specify any of the other parameters) and give it a try. This is a new feature in build 3588 and it looks like it is not working as expected with one of your SFTP servers. Several other users also reported problems with this feature and it will be turned off by default in the next release.

If this doesn't help, please send us the communication log created using the Sftp object's LogWriter property (as described here)

Update: The current release (build 3723) has ZLIB compression disabled by default.

I can verify that this answer also works very well for the same error in SCP.

Yes, the underlying SSH library is the same. It also works for Rebex SSH Shell.
