Continue_on_error with smtp and rest command service

Configuration
1

Dear all, i’m using last HA version and i 'm encountering problems with an automation with continue_on_error function. With internet connection all is working well but sometimes the connection goes down and the automation stops working. This is my code:

- alias: ALARM-WATER
  initial_state: false
  trigger:
  - platform: state
    entity_id: binary_sensor.alarm_bilge
    to: 'on'
  condition:
  - condition: state
    entity_id: input_boolean.alarm_water
    state: 'on'
  action:

  - continue_on_error: true
    repeat:
      until:
      - condition: template
        value_template:  '{{ repeat.index >= 20  }}'

      sequence:
####################################################
# BUZZER ON
####################################################
      - service: switch.turn_on
        continue_on_error: true
        data: {}
        entity_id: switch.buzzer

      - service: persistent_notification.create
        data:
          title: ALARM
          message: "<b>ALARM WATER!</b>"
      - delay: 00:00:01
####################################################
#  SMS
####################################################
      - service: rest_command.sms_allarm_water
        continue_on_error: true
        data: {}
      - delay: 00:00:01
####################################################
# MAIL
####################################################
      - service: notify.mail
        continue_on_error: true
        data:
          message: 'ALARM WATER'
          title: ALARM
      - delay: '00:00:10'


  - service: switch.turn_off
    data: {}
    entity_id: switch.buzzer
  - service: persistent_notification.create
    data:
      title: INFO
      message: "STOP NOTIFICATIONS"
  mode: single

I put continue_on_error everywhere but no luck…
Could someone point me in the right direction??

Thanks a lot.
