Failed to open browser automatically: {err}

Error message

Failed to open browser automatically: {err}

What it means

When ConfigUiMode::Web starts the browser-based config editor and automatic browser launch fails, a System message with this text is added to the transcript. The web editor itself is running; only the convenience launch failed, so the user is told to open the printed URL themselves — a UI-level degradation, not a config-editor failure.

Solutions

1. Open the config UI URL shown in the transcript manually
2. Install or fix the default-browser handler (xdg-open/open) if auto-launch is wanted
3. Ignore if you only need the server; the editor remains reachable at the URL
