This guide will explain diagnostic methods and solutions for each type of issue, helping you quickly restore normal operation.

Connection Issues Troubleshooting

Connection issues are the most common ClashX failures. This section explains how to diagnose and resolve these problems.

Issue 1: Cannot Connect / Proxy Not Working

Симптомы

• Applications cannot access the internet
• Connection timeout errors
• ClashX is running but has no effect

Troubleshooting Steps

# 在终端中检查是否有 ClashX 进程
ps aux | grep clash

# 输出示例：
# xxx /Applications/ClashX.app/Contents/MacOS/ClashX

# 检查 ClashX 是否正常监听端口
lsof -i :7890
lsof -i :7891

# 测试代理连接
curl -x http://127.0.0.1:7890 http://www.gstatic.com/generate_204

Issue 2: Тайм-аут подключения

Симптомы

• Connection normal but response slow
• Large file downloads failing
• Some websites cannot load

Решение

# 编辑 config.yaml，在通用设置中添加：
protocol: TLS1.2

# TCP 连接超时（秒）
connect-timeout: 5

# 读取超时（秒）
read-timeout: 5

# 如果仍然超时，尝试增加到：
connect-timeout: 10
read-timeout: 10

Issue 3: Intermittent Connection Drops

Симптомы

• Connection randomly drops during use
• Need to restart ClashX to recover
• Particularly unstable during certain times

Решение

• Update Nodes: Manually update ссылка подписки, remove unstable nodes
• Switch Протокол: Try different протокол проксиs (SS, Trojan, VMess)
• Check Router: Restart сеть devices, check connection stability
• Enable Keep-Alive: Enable TCP Keep-Alive in configuration

proxies:
  - name: "稳定节点"
    type: ss
    server: example.com
    port: 443
    cipher: aes-256-gcm
    password: "password"
    udp: true

    # 启用 Keep-Alive
    keep-alive: true

Режим TUN Issues

режим TUN is a system-level proxy that does not require separate configuration for each application. However, it can also cause issues.

Issue 1: Режим TUN Cannot Be Включено

Common Errors

Troubleshooting Steps

# 检查当前用户是否为管理员
id

# 查看 ClashX 权限
ls -la /Applications/ClashX.app/Contents/MacOS/ClashX

Решения

1. Ensure using administrator account
2. Grant TUN permissions in ClashX settings
3. Try using gvisor протокол stack (more stable)
4. Check for conflicts with other VPN software

Issue 2: No Сеть After Enabling Режим TUN

Симптомы

• Completely no сеть after enabling режим TUN
• Local IP address displays abnormally
• DNS resolution failed

Quick Recovery

# 强制禁用 TUN
defaults write com.west2online.ClashX tun-enabled -bool false

# 重启 ClashX
killall ClashX

Configuration Fix

tun:
  enable: true
  stack: gvisor          # 推荐 gvisor
  dns-hijack:
    - any:53             # 劫持所有 DNS 查询
  auto-route: true       # 自动设置路由
  auto-detect-interface: true

# DNS 配置
dns:
  enable: true
  listen: 127.0.0.1:53
  enhanced-mode: fake-ip
  nameserver:
    - 119.29.29.29
    - 223.5.5.5

Issue 3: Режим TUN Affecting Other Applications

Симптомы

• Some apps (like iMessage, Apple Music) cannot function normally
• Local services (like MySQL, Redis) connection failed
• VoIP apps have no audio

Решение

# 在 config.yaml 中配置
tun:
  enable: true
  stack: gvisor
  dns-hijack:
    - any:53
  auto-route: true
  auto-detect-interface: true

  # 流量过滤 - 不走 TUN 的应用
  include-apps:
    - com.apple.dt.Xcode
    - com.docker.docker

  # 不走 TUN 的网络接口
  exclude-interfaces:
    - en1
    - en2

Подписка Link Issues

Подписка links are an important way to configure ClashX. Common подписка issues include import failures and nodes not displaying.

Issue 1: Подписка Import Failed

Симптомы

• No response after pasting link
• Displays "Invalid URL"
• Configuration file empty after import

Troubleshooting Steps

# 检查链接是否有效
curl -I "https://example.com/subscribe"

# 验证返回的内容类型
curl -I -H "Accept-Encoding: gzip" "https://example.com/subscribe"

Common Causes & Solutions

Issue 2: Подписка Update Failed

Симптомы

• No response when clicking update button
• Displays "Update failed"
• Nodes remain old list

Решение

Issue 3: Nodes Not Displayed in Подписка

Симптомы

• Подписка imported but no available nodes
• proxy-groups is empty
• Rules cannot match

Check Process

# 打开配置文件
open ~/.config/clash/config.yaml

# 检查以下内容：
# 1. proxies 部分是否有节点
# 2. proxy-groups 是否正确
# 3. rules 是否完整

Common Reasons

• Подписка link format incompatible with ClashX
• Node information incomplete or format error
• Proxy протокол version not supported
• YAML syntax error

Производительность Оптимизация

ClashX производительность issues usually manifest as slow speed, high память usage, and high CPU usage.

Issue 1: Slow Proxy Speed

Симптомы

• Slow web page loading
• Video buffering
• File download speed lower than normal

Troubleshooting Steps

# 在 ClashX Dashboard 中进行测速
# 或使用命令行工具测试
curl -x socks5://127.0.0.1:7891 http://www.gstatic.com/generate_204 -w "%{time_total}\n" -o /dev/null

# 检查到不同地区的延迟
ping -c 4 8.8.8.8  # 需要代理设置

Оптимизация Solutions

• Select Optimal Node: Use url-test to automatically select lowest latency node
• Adjust DNS: Use low-latency DNS серверы
• Enable Multiplexing: Enable HTTP/2 on supported protocols
• Check Local Сеть: Ensure Wi-Fi signal is stable

# 使用 url-test 自动选择快速节点
proxy-groups:
  - name: "♻️ 自动选择"
    type: url-test
    proxies:
      - "节点1"
      - "节点2"
      - "节点3"
    url: "http://www.gstatic.com/generate_204"
    interval: 300        # 每 5 分钟测试一次
    tolerance: 50        # 50ms 容差

# 优化 DNS 配置
dns:
  enable: true
  enhanced-mode: redir-host  # 比 fake-ip 性能更好
  nameserver:
    - 119.29.29.29       # 快速的国内 DNS
    - 223.5.5.5
  fallback:
    - https://1.1.1.1/dns-query  # 快速国际 DNS

Issue 2: High Память Usage

Симптомы

• ClashX using more than 500MB память
• System becomes sluggish
• Other applications respond slowly

Решение

• Reduce Node Count: Delete unused nodes and набор правилs
• Disable Unnecessary Features: Turn off Dashboard, режим TUN
• Optimize Rules: Use набор правилs instead of individual rules
• Regular Restart: Restart ClashX daily to free память

Monitor Память Usage

# 查看 ClashX 的实时内存使用
top -p $(pgrep ClashX)

# 导出内存占用详情
ps aux | grep ClashX

Issue 3: High CPU Usage

Симптомы

• ClashX process CPU usage over 50%
• Fan spinning fast
• Battery draining quickly (laptop)

Решение

• Check Rule Complexity: Too many rules increase CPU burden
• Disable Fake-IP: Use redir-host mode
• Limit url-test Frequency: Increase test interval
• Update to Latest Version: New versions usually have производительность optimizations

dns:
  enable: true
  enhanced-mode: redir-host  # 而不是 fake-ip

# 减少日志级别
log-level: warning

# 降低测试频率
proxy-groups:
  - name: "♻️ 自动选择"
    type: url-test
    interval: 600  # 增加到 10 分钟
