Installing the client only deploys the program. To establish a connection, import a valid configuration, choose a proxy mode, and verify the routing result. Follow the order below to distinguish installation issues from configuration issues.
1
Import a subscription or individual node
On desktop, create a group under “Subscription Groups,” enter the subscription URL, and update it. On mobile, add the URL in Subscription Settings or import an individual configuration link from the clipboard. After importing, check that the protocol, address, port, and transport parameters are complete.
2
Choose a system proxy mode
For browsers and desktop apps that follow system proxy settings, start with “Set system proxy automatically.” Configure TUN mode only when more apps need coverage or when connections ignore the system proxy. Do not change routing, DNS, and TUN simultaneously during the first test; multiple changes expand the troubleshooting scope.
3
Configure routing and DNS
For standard traffic splitting, start with the “Bypass mainland China” preset rules, then add domain or process rules as needed. DNS settings must match the current proxy mode: system proxy mainly affects apps that honor proxy settings, while TUN also captures broader network traffic and DNS requests.
4
Verify the connection and routing
Open a website that requires a proxy to confirm the connection, then visit a site that should connect directly to check routing. If the connection fails, inspect the client log and distinguish subscription update failures, incorrect node parameters, inactive system proxy, DNS errors, and local security-software restrictions.
