Fix FetchError

✅ Solution

FetchError in Vercel CLI often indicates network connectivity issues preventing secure connections, such as a firewall, proxy, or TLS incompatibility. Try disabling your VPN/proxy, ensure your system's TLS version is up-to-date (at least TLS 1.2), or check if your firewall is blocking Vercel CLI. As a last resort you can try setting `NODE_TLS_REJECT_UNAUTHORIZED=0` (though this is less secure and should only be used for testing).
