[thedarkknight197]

I am running searxng how is described in readme.md. from browser it work correctly.

I need to integrate with that: https://www.npmjs.com/package/n8n-nodes-searxng in my n8n local running container.

so i added my network to attach my instance:

  caddy:
    container_name: caddy

    external: true
    name: n8n_default
