  2. If the no value is defined, update the key vwith the Tableau Server FQDN. For example, if Tableau Server is reached by entering https://tableau.example.com in the browser, enter this command:
    tsm configuration set -k gateway.public.host -v "tableau.example.com"
  3. Commit the configuration change:
