Failed to fetch ${url}: ${response.status}
Error message
Failed to fetch ${url}: ${response.status} What it means
parseYml in the electron updater fetches a remote YAML update manifest and throws 'Failed to fetch ${url}: ${response.status}' when the HTTP response is not ok. The update-manifest endpoint returned a non-2xx status (404, 403, 500, etc.), so version metadata for win/mac could not be loaded.

Solutions
- Open the exact URL in a browser/curl to confirm the status code and fix the hosted YML file or URL.
- Check update channel configuration (version, channel, provider URL) matches the published artifacts.
- Retry if the status is 5xx — it may be a transient server error.
- Add a fallback update mirror or cached manifest.
Example fix
// before
const response = await fetch(url);
if (!response.ok) throw new Error(`Failed to fetch ${url}: ${response.status}`);
// after
const response = await fetch(url);
if (!response.ok) {
if (response.status >= 500 && attempt < 3) return retry(url, attempt + 1);
throw new Error(`Failed to fetch ${url}: ${response.status}`);
} Defensive patterns
Strategy: retry
Validate before calling
const head = await fetch(url, { method: 'HEAD' });
if (!head.ok) throw new Error(`更新清单不可用: ${url} -> ${head.status}`); Try / catch
try {
const yml = await parseYml(url);
} catch (e) {
if (e.message.includes('404')) throw new Error('更新清单缺失,请检查发布产物 latest.yml');
if (e.message.includes('403')) throw new Error('更新清单被拒绝访问,请检查URL签名/权限');
throw e; // 5xx 可重试
} Prevention
- Verify latest.yml / latest-mac.yml exist on the release server after each deploy.
- Monitor the manifest URL with a HEAD request health check.
- Keep a cached/fallback manifest mirror for resilience.
- Match channel/provider config to the published artifact names.
When it happens
Trigger: fetch(url) returns response.ok === false — the update YML URL points to a missing/renamed file, requires auth, is blocked by CDN/firewall, or the server errors.
Common situations: Latest.yml / latest-mac.yml missing on the release server after a deploy; wrong base URL or channel in update config; CDN geo-blocking; expired signed URLs returning 403.
