Smtp stopped working

Hi.
Today after home assistant restart gmail smtp stopped working with error: “Error executing script. Service not found for call_service at pos 1: Unable to find service notify.sms”

notify:
  - name: SMS
    platform: smtp
    server: smtp.gmail.com
    port: 587
    timeout: 15
    sender: [email protected]
    encryption: starttls
    username: [email protected]
    password: hidden
    recipient:
      - hidden@hidden

Another home assistant restart resolved the issue.
