Symptom:

  • fzSftp started, protocol_version=9
    FATAL_ERROR: Network error: Software caused connection abort
    Could Not connect to server

Path to resolution:

  • Ensure that the correct port was used
  • Run test-netconnection $computername -port $portNumber to verify that port and network route are available
  • Check the firewall. For example, Sonicwall has this feature ‘Remote-Access SSH Generic Protocol Detection’ that would block certain contents.
