Downloading the file is only the first step. Verify the subscription, proxy groups, and traffic routing separately so configuration issues aren’t mistaken for installer problems.
Import a configuration before enabling the proxy
Add a link through the client’s configuration or subscription manager, update it, and set that configuration as active. If you import a local YAML file, check indentation, file encoding, and paths to external rule files. The client doesn’t provide proxy servers automatically; verify the subscription source, expiration, and access permissions. Keep credentials in subscription links private—don’t include them in public screenshots or support posts.
Check ports and rule mode
The configuration’s mixed-port is commonly used for combined HTTP and SOCKS listening, but the actual value depends on the configuration and client overrides. Don’t assume every client uses the same port. In rule mode, connections are matched in rules order; you also need to choose an available policy in the relevant proxy group. Check connection logs to see which rule matched, not just whether the interface says the client is running.
System proxy vs. TUN
The system proxy works with apps that follow the operating system’s proxy settings; some command-line tools, games, and Store apps may ignore them. TUN handles traffic at the virtual network interface layer and requires additional permissions. It may also conflict with routes from other VPNs, virtual adapters, or security software. Test the basic configuration with the system proxy first, then enable TUN if needed. Avoid changing multiple network layers at once so you can still identify the cause of problems.
Keep a recoverable setup before updating
Record your current client settings and back up custom rules, overrides, and subscription sources. After updating, first verify that the original subscription loads, then restore local changes. Version labels describe the app release; installer filenames may also include a platform build number, so they don’t always match. When troubleshooting, note the app version, actual filename, and CPU architecture. See the Clash Meta Getting Started guide for the full workflow, or Troubleshooting for connection issues.
