**Toggle the iOS VPN setting off and on, or reboot your iPhone to clear stale VPN state and restore Shadowrocket connectivity.**

Shadowrocket (小火箭) is a popular iOS client supporting Shadowsocks, ShadowsocksR, and VMess protocols, but users frequently encounter connection failures due to stale VPN states or outdated configurations. This guide leverages the official documentation from the `bannedbook/fanqiang` repository to provide authoritative solutions for resolving connectivity issues. Whether you are importing V2Ray nodes or configuring advanced routing rules, these steps address the root causes of iOS VPN tunnel failures.

## Understanding Shadowrocket's VPN Architecture

Shadowrocket stores VPN configurations locally within iOS's network extension framework. When the system-level VPN state becomes desynchronized—common after network switches or app updates—the tunnel fails to establish even with valid server credentials. According to [`ios/Shadowrocket.md`](https://github.com/bannedbook/fanqiang/blob/main/ios/Shadowrocket.md), the app requires a manual reset of the VPN interface or a full device restart to clear corrupted state caches that block the tunnel.

## Prerequisites for Connection Stability

Before troubleshooting connection failures, verify two foundational requirements documented in [`ios/AppleID.md`](https://github.com/bannedbook/fanqiang/blob/main/ios/AppleID.md):

- **Valid U.S. Apple ID**: Shadowrocket is a paid application removed from the Chinese App Store. You must use a U.S. Apple ID to purchase and download the app.
- **Latest App Version**: Ensure you are running the most recent Shadowrocket build from the App Store, as older versions contain protocol-handling bugs that prevent successful handshakes.

## Step-by-Step Connection Fixes

### Import V2Ray Subscription Nodes

The primary connection method uses subscription URLs. The workflow in [`ios/Shadowrocket.md`](https://github.com/bannedbook/fanqiang/blob/main/ios/Shadowrocket.md) (lines 48-60) specifies:

1. Navigate to **Settings → Server Subscription** and enable **"打开时更新"** (Update on Open).
2. Tap the **+** button and select **Subscribe**.
3. Paste your subscription URL into the address field.

```markdown
Settings → Server Subscription → "打开时更新" ON → + → Subscribe → [Paste URL]

```

Treat the subscription URL as a password; exposure compromises your node security according to lines 44-45 of [`ios/Shadowrocket.md`](https://github.com/bannedbook/fanqiang/blob/main/ios/Shadowrocket.md).

### Force-Update Node Lists

After adding a subscription, manually refresh the node list to ensure current server availability:

```markdown
Server List → Tap "i" icon next to subscription → 完成 (Done)

```

This triggers an immediate fetch from the remote subscription endpoint, as implemented in lines 64-66.

### Reset VPN State (The Toggle Fix)

When Shadowrocket shows **"未连接"** (Not Connected) despite valid nodes, execute the system VPN reset documented in [`ios/Shadowrocket.md`](https://github.com/bannedbook/fanqiang/blob/main/ios/Shadowrocket.md) (lines 20-25):

**Method 1: Toggle VPN Interface**
- Open iOS **Settings → VPN**.
- Toggle the VPN switch **OFF**, wait 3 seconds, then toggle **ON**.

**Method 2: Device Reboot**
- Power off the iPhone completely.
- Restart the device and reopen Shadowrocket.

These actions purge stale VPN configurations from the iOS network stack that prevent tunnel establishment.

## Advanced Routing Configuration

### Implementing Comprehensive Split-Rules

If default routing fails to capture all target domains, import the Hackl0us rule set as a remote configuration file:

```markdown
Remote URL: https://raw.githubusercontent.com/Hackl0us/Surge-Rule-Snippets/master/LAZY_RULES/Shadowrocket.conf

```

According to [`ios/Shadowrocket.md`](https://github.com/bannedbook/fanqiang/blob/main/ios/Shadowrocket.md) (lines 87-94):

1. Add the URL as a remote file in the **配置** (Config) screen.
2. Apply the configuration as your active routing set.
3. Select **Settings → 延迟测试方法 → CONNECT** to verify latency and run **连通性测试** (Connectivity Test) to confirm traffic routing through the selected node.

## Summary

- **Stale state causes failures**: Shadowrocket connection problems often stem from desynchronized iOS VPN caches, not server-side issues.
- **Reset fixes most issues**: Toggling the VPN switch in iOS Settings or rebooting the device clears corrupted states without reconfiguration.
- **Subscription hygiene**: Always import V2Ray nodes via the Subscribe method and force-update after URL changes to maintain current server lists.
- **Advanced rules**: Load remote configurations from trusted repositories like Hackl0us for comprehensive domain routing when default rules fail.
- **Purchase requirements**: A U.S. Apple ID is mandatory for acquiring Shadowrocket from the App Store, per [`ios/AppleID.md`](https://github.com/bannedbook/fanqiang/blob/main/ios/AppleID.md).

## Frequently Asked Questions

### Why does Shadowrocket fail to connect after working previously?

iOS occasionally retains corrupted VPN tunnel states when switching between Wi-Fi and cellular networks. According to [`ios/Shadowrocket.md`](https://github.com/bannedbook/fanqiang/blob/main/ios/Shadowrocket.md), toggling the VPN setting off and on in iOS Settings (lines 20-23) or performing a full device reboot (lines 24-25) clears these stale configurations and restores connectivity by reinitializing the network extension.

### How do I add a subscription URL to Shadowrocket?

Navigate to **Settings → Server Subscription**, enable **"打开时更新"**, then tap the **+** button and select **Subscribe**. Paste your subscription URL into the provided field and tap **Done**. This method, documented in [`ios/Shadowrocket.md`](https://github.com/bannedbook/fanqiang/blob/main/ios/Shadowrocket.md) (lines 48-60), automatically pulls the latest V2Ray nodes whenever you open the app.

### What should I do if the default routing rules don't work?

Download a comprehensive rule set from the Hackl0us repository using the remote file URL `https://raw.githubusercontent.com/Hackl0us/Surge-Rule-Snippets/master/LAZY_RULES/Shadowrocket.conf`. Import this as a remote configuration in the **配置** screen, as detailed in [`ios/Shadowrocket.md`](https://github.com/bannedbook/fanqiang/blob/main/ios/Shadowrocket.md) (lines 91-94), to ensure proper traffic splitting for all target domains.

### Is a U.S. Apple ID mandatory for using Shadowrocket?

Yes. Shadowrocket is a paid application unavailable in the Chinese App Store. The [`ios/AppleID.md`](https://github.com/bannedbook/fanqiang/blob/main/ios/AppleID.md) file provides a complete guide for creating a U.S. Apple ID without a credit card (lines 1-14 and 45-46), which is required to purchase and download the application.
