Three checks to make before and after downloading
Installers, client updates, and subscription updates
The installer provides the client and its bundled components; the subscription provides available proxies, policy groups, and rules. Updating the client won’t fix an expired subscription, and refreshing a subscription won’t update the client. Download buttons retain their full file links and use links from the download manifest when it’s available on the page. Client version details appear only when the manifest contains valid data. Check the platform and architecture you selected to confirm the package name.
Verify a basic connection before changing network routing
For a first installation, import one configuration from a trusted source, select rule mode, choose a proxy policy group, then test with the system proxy or your mobile device’s VPN connection. Once basic requests work, configure TUN, DNS overrides, and per-app routing as needed. Changing ports, DNS, policy groups, and routes all at once makes problems harder to isolate. See the setup guide for full instructions and proxy modes for the differences between modes.
Keep configurations recoverable when migrating
Before switching clients, note your subscription source and record any manually added rules and local overrides you need. Screenshots alone usually aren’t enough to restore a complete configuration. Turn off the old client’s system proxy and TUN before starting the new one. Once connections, DNS resolution, and rule matching work, clean up the old setup. Subscription links and configurations may contain access credentials; keep backups somewhere secure and share only the necessary, sanitized details when troubleshooting.
