Unable to navigate in the UI, receiving the error "Unable to establish protocol connection to local host after update"

RESOLUTION

Use an SSH client such as  PuTTY to access the Unitrends system at the command line level.  Note:  Ensure you have the OS password to access the Unitrends system’s command line.  The OS  password may differ from the password used to access the User Interface.

  1. First, make a copy of your existing hosts file.
#cp /etc/hosts /etc/hosts.bak
  1. Add or correct the localhost entry in the system hosts file using the vim editor.  For more details on how to edit using vi, see EDITING FILES WITH VI.
#vi /etc/hosts
  1. Find the entry for localhost and edit it such that is exactly mirrors the example below.
127.0.0.1         localhost.localdomain localhost
The UI should not operate normally.
