SMS.3802 Failed to Establish an SSH Connection with the Target Server

During a migration, an SSH connection must be established between the source server and target server. This error message is displayed when the SSH client reports the error "SSHException", indicating that an exception occurs during SSH connection setup. The possible causes and solutions are:

• The currently installed SMS-Agent is not the latest version.

  Go to the Agents page on the SMS console, download and install the latest SMS-Agent, and create a migration task again.

• Security software or firewalls may block the connection from the source server to the target server.
  • Check the firewall settings of the source server and ensure that no outbound traffic is intercepted If the traffic is blocked, enable the involved ports and try again.
  • Check whether there is security software running on the source server. If there is, disable the security software, stop related services if necessary, and try again.
