Error message

HTTP ${resp.status}

What it means

Browser-mode connection test fetches `${url}/system_stats` with mode: 'cors' and throws on any non-OK status. ComfyUI commonly returns 403 when started without --cors-allow-origins for the app origin; other codes indicate a wrong port/path or an authenticating proxy. Network-level failures (refused, DNS, CORS) surface separately as a fetch TypeError, which the catch below classifies via isCorsError.

Solutions

1. Restart ComfyUI with --cors-allow-origins matching the app origin (or '*' for local testing).
2. Verify the URL/port and that /system_stats responds (curl it from the same machine).
3. Prefer the Electron app, whose main-process proxy bypasses CORS entirely.
4. Check the isCorsError branch for the distinct network/CORS TypeError case.

const url = comfyuiServerUrl.value.replace(/\/+$/, '')
if (!/^https?:\/\//.test(url)) {
  connectionInfo.value = 'Enter a valid http(s) URL'
  connectionStatus.value = 'failed'
  return
}

catch (e) {
  const msg = errorMessageFrom(e) ?? ''
  if (msg.startsWith('HTTP '))
    connectionInfo.value = `ComfyUI returned ${msg} — check CORS flags and URL`
  else if (msg.includes('fetch') || msg.includes('CORS'))
    isCorsError.value = true
  connectionStatus.value = 'failed'
}

When it happens

Trigger: ComfyUI running without CORS flags; URL with wrong port or path (404); a reverse proxy returning 401/502; an older ComfyUI build without /system_stats.

Common situations: Testing stage-web against a local or remote ComfyUI from the browser instead of the Electron app; ComfyUI defaults not allowing the app origin.
