Hey i got a issue with my new Docker Compose:

version: '3.8'

volumes:
  db_storage:
    external: true
    name: n8n-postgres_db_storage
  n8n_data:
    external: true
    name: n8n-postgres_n8n_data
  redis_storage:

  n8n-worker-3:
    <<: *n8n-worker-template

networks:
  n8n-net:
    driver: bridge
    ipam:
      config:
        - subnet: 172.21.0.0/16

Webhooks are working fine with the domain but the Error Trigger outputs:

“http://localhost:5678/workflow/Jbe7iKKIMiBAj0XJ/executions/73216”,

just like the smtp approve buttons in a mail it points to localhost:5678/xxxx

im not even using the Port 5678 in my Docker Compose

can someone help me and fix my docker compose?

Just a hunch (haven’t tried this to see), but the first thing I would try is duplicating the URL-related environment variables in the main node to the worker nodes.

      - N8N_PORT=5679
      - N8N_PROTOCOL=https
      - WEBHOOK_URL=${WEBHOOK_URL} // -> https://redacted.domain.com/

Oh yes, I’m stupid. Thanks, I thought I had already tried that.
