After installation
Configuration, permissions, and migration checks
The installer only installs the program. A working connection also depends on your configuration, proxy policy, and traffic-routing method.
First, make sure the configuration loads
Import an existing subscription or local YAML file, then check which configuration is active. If you see a syntax error, missing proxy group, or failed rule reference, fix that before enabling the system proxy. Subscription URLs often contain access credentials; store them securely and hide sensitive parts before sharing log screenshots.
Then choose how to route traffic
A desktop system proxy mainly affects apps that follow system settings. Command-line tools, games, and apps with their own network stack may need separate configuration. TUN routes traffic through a virtual network interface and also affects routing and DNS settings. For your first setup, verify a simple connection path. Once rules and proxy groups work, enable TUN, per-app proxying, or launch at startup as needed.
Back up recoverable settings before upgrading
Quit the old client and export custom rules, overrides, and key settings before installing the new version. Don’t copy one product’s entire data directory over another’s. Import the base subscription first, confirm it works, then restore additional settings one by one. If the system proxy still points to an old port, apps may fail to connect even when the new client is running.
For setup steps, see the first-time setup guide. For details on rules, DNS, TUN, and maintenance, read the user guide. If you’re unfamiliar with architecture or configuration terms, start with the glossary.
