  • Connection failure with SFTP

    We're getting the following "connection failure" message when attemping to use the "SFTP Reader" connector. Using an SFTP client (Core FTP) works just fine. Any insights would be greatly appreciated.

    Re:Connection failure with SFTP

    I've investigated a bit further and am wondering if there is something (undocumented) about the configuration, and specifically how Mirth creates the connection string for Mule (the open source library for SFTP, and others). Mule was a connection string that looks like, "sftp://user[email protected]/path/to/dir". The log file only shows "sftp://host", yet I have populated the Username, Password, and Move-to fields in Mirth.

    Am I missing something?
