Keep your old configuration before replacing anything
Before upgrading or switching clients, export your current configuration and save custom rules, overrides, and any important interface settings. Remote subscription updates typically replace only the subscription content; whether local changes are retained depends on the client’s configuration management. Don’t copy an old app’s entire data directory into the new client’s folder.
Choose a proxy group after importing your configuration
Prepare a subscription URL you’re authorized to use or a local configuration file. Import it on the Configuration page and set it as active. Open the Proxy page to check your proxy groups, start in rule mode, then enable the traffic routing method suited to your system. If importing fails, check the URL, authorization, and network instead of repeatedly reinstalling the client.
Use logs to tell traffic interception issues from rule issues
Check the logs after visiting a site. If there’s no corresponding connection, check whether the app is routed through the proxy. If there is a connection but the wrong policy is used, review the matched rule and proxy group. If the rule matches but the connection still fails, check the destination and DNS. The system proxy doesn’t cover every app, and TUN isn’t a universal fix.
