Unable to connect via SFTP
  • I'm getting:
    "Connecting to server...
    "Error 4640,800 Timeout"
    when attempting to connect via SFTP to a remote macOS host.

    I can successfully connect via SSH and SFTP in Terminal using same name/password
    Nothing is written to the Security Spy log
    Security Spy 5.1.0

    Any suggestions to troubleshoot would be welcome.

  • Hi Dave, could you please try this with the latest beta version of SecuritySpy (currently 5.1.1b20) and let me know if this fixes it? Thanks.
  • Hi Ben,

    That seems to work; I'll push the testing a little harder when I get a chance later todayl

    Thanks!
