_Originally opened as a discussion at https://github.com/github/vscode-github-actions/discussions/127_

Start by reproducing the hover failure in the GitHub Actions Language Server and review the logged requests to api.github.com for action metadata and the current user. The issue points to dist/server-node.js in the extension; use the ETIMEDOUT traces and the expected no-error behavior to define and verify the fix.
