 ## Troubleshooting
 
-If you encounter an "Unable to authenticate" error when publishing, first verify that the workflow filename matches exactly what you configured on [npmjs.com](https://npmjs.com), including the `.yml` extension. All fields are case-sensitive and must be exact. Also ensure you're using GitHub-hosted runners, GitLab.com shared runners, or CircleCI cloud, as self-hosted runners are not currently supported. For GitHub Actions specifically, check that the `id-token: write` permission is set in your workflow. For CircleCI, verify that your Organization ID, Project ID, and Pipeline definition ID match your CircleCI configuration.
