FYI I was getting errors with pipelines using a directory browser with a basic auth account for SFTP. After doing some testing and verifying the authentication details I ended up rolling back the Binary Snap Pack version to Main19844. Problem was resolved - must be a bug in new version.
The error I was getting is
Failure: Unable to create filesystem object for sftp://sftp.accorplus.com:2222/, Reason: Failed to get SFTP session connected, Resolution: Please check all properties and credentials
