Workflow Yml Used

name: Latest blog post workflow
on:
  schedule: # Run workflow automatically
    - cron: '0 * * * *' # Runs every hour, on the hour
  workflow_dispatch: # Run workflow manually (without waiting for the cron to be called), through the GitHub Actions Workflow page directly
permissions:
  contents: write # To write the generated contents to the readme

jobs:

    steps:
      - name: Checkout

Additional context

I think it may be a connection error. I tried follow url's (they are all the same website), the issue is still there

https://blog.musnow.top/atom.xml    # cdn
https://blog1.musnow.top/atom.xml  # netlify
https://musnows.github.io/atom.xml  # github pages

@musnows it is because one of your posts doesn't have a title in the RSS feed. This is not a bug. You can fix it in your website or you can use the following:

name: Latest blog post workflow
on:
  schedule: # Run workflow automatically
    - cron: '0 * * * *' # Runs every hour, on the hour
  workflow_dispatch: # Run workflow manually (without waiting for the cron to be called), through the GitHub Actions Workflow page directly
permissions:
  contents: write # To write the generated contents to the readme

          disable_item_validation: true
          item_exec: "if (!post.title) post = null;" #to skip posts that don't have title
