Clash TUN Doctor

Evidence-first diagnosis and reversible repair for application networking failures behind Clash Verge Rev TUN mode.

When to Use

• An application works without TUN but fails, stalls, or loses media with TUN.
• WeChat text works while image uploads or Moments images fail.
• A rule change makes the symptom worse or the app remains stuck on Loading.
• The subscription says ipv6: false, but runtime traffic still uses IPv6.
• Clash logs contain no route to host, context deadline exceeded, or an unexpected rule/strategy for the affected process.

Do not use this skill for generic subscription acquisition, node purchasing, or bypassing organizational network policy.
