Subscribe and server management
Server details, subscriptions, and rule configurations serve different purposes. Before importing anything, identify what kind of information you have.
What they are: A server entry stores the address, port, protocol, and authentication details needed to connect. Subscribe updates a group of server entries from a subscription URL you already have. Config stores settings such as routing rules. A successful subscription update means the content was fetched and parsed; it doesn't guarantee that every server can connect or that any related rules are enabled.
Where to find them and how to set them: Manage servers in the SERVER section on Home. Use Add Server to choose the type that matches your existing details. When entering information manually, check the address, port, password, and other authentication fields one by one. Use Scan QR Code to import an existing QR code, or add an existing subscription from the Subscribe menu. Confirm that the group and entries appear, then run Connectivity Test on a server and establish a connection to verify an actual request.
The protocol must match the server details you already have, such as Shadowsocks, VMess, VLESS, Trojan, WireGuard, or Hysteria2. Don't change it just to make a test pass. Check transport settings, TLS, server name, and other fields against the original information; these aren't universal options that can all be left blank. If a field is missing, check the original details rather than copying settings from another server.
Keep in mind: Updating a subscription can refresh entries, names, or groups. Record important manual changes separately and confirm how they are saved. Before deleting a group, check whether it contains servers you added individually. Subscription URLs and QR codes may contain authentication details; hide the full link, passwords, and identifying fields before sharing screenshots or diagnostics. If a test fails, keep the original entry and edit a copy so you can compare settings and restore them if needed.
