I have a SFTP connection to a site with a private/public key. I keep getting an error “FTP operation Failed: Failure establishing ssh session” WHen I look in the logs its a CURL (2) error. However, randomly messages are crossing. 1 message will cross everyday. But then it will sit in an error status?? Any suggestions on how to get it out of the error status and allow messages to cross on a more structured basis.
