My configuration is

notify_when_doorbell_on_day:
  sequence:
  - data:
      data:
        attachment:
          content-type: jpeg
          hide-thumbnail: false
          url: http://192.168.0.122:58738/snapshot.cgi?user=admin&pwd=kunyai11820&res=0
        push:
      message: Someone ring the doorbell!
    service: notify.mobile_app_vip

First time I use this config. It’s work like a charm, but today picture doesn’t appear. I don’t know what happen?
