500 Internal Error // Faraday::ConnectionFailed

Hello, I recently cam across your project, while testing it out I'm having some issues. I created a folder with two files:

docker-compose.yml

version: "3"
services:
  html2rss-web:
    image: gilcreator/html2rss-web
    ports:
      - "3000:3000"
    volumes:
      - type: bind
        source: ./feeds.yml
        target: /app/config/feeds.yml
        read_only: true
    environment:
      - RACK_ENV=production
      - HEALTH_CHECK_USERNAME=health
      - HEALTH_CHECK_PASSWORD=please-set-YOUR-OWN-veeeeeery-l0ng-aNd-h4rd-to-gue55-Passw0rd!

and

feeds.yml

stylesheets:
  - href: "/rss.xsl"
    media: "all"
    type: "text/xsl"
headers:
  "User-Agent": "Mozilla/5.0 (Windows NT 10.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/108.0.0.0 Safari/537.36"
feeds:
  # your custom feeds go here:
  example:
    channel:
      url: https://www.reuters.com/technology/
      language: en
      ttl: 360
      time_zone: UTC
    selectors:
      items:
        selector: '[class^="story-collection"] > li'
      title:
        selector: h3
      link:
        selector: a:first
        extractor: href
      description:
        selector: p

No matter which config example, it returns the same error (this is a screenshot when using 120 commits config):

These are the logs:
