When setting up a VPN, it’s easy to confuse three separate things: successful payment, a successfully imported subscription, and an active client connection. To get online, your account, plan, client, and actual traffic all need to work together. If you’ve already placed an order, start by checking your plan. If you don’t have an account yet, follow the steps in order—there’s no need to study every protocol first.
Account and order: Confirm your service is active
S4VPN requires no email address. Create an account with a username and password through the account portal, and save your login details in a password manager. Make sure the username belongs to the account used for your order. If you’ve switched accounts in your browser, check which one you’re signed in to before mistaking an empty dashboard for a missing order.
If you’ve paid, open the dashboard overview and check your plan status, remaining data, and whether the service is active. A success message on the payment page only confirms that the payment flow reported success; check the dashboard to see whether your service is ready to use. S4VPN accepts Alipay, WeChat Pay, and USDT. For payment issues, refer to the actual transaction record for the method you used.
What to expect: The dashboard shows the plan matching your order, and your account is ready to use. Common issues: The page hasn’t refreshed after payment, you’re signed in to a different account, or the order status hasn’t updated yet. Reopen the overview and check the order. Don’t place another order just because the client doesn’t show any routes yet. If you still have questions, submit your order details through a support ticket. Share payment records only through an approved support channel.
Check your plan: Monthly subscription or data package
When getting started, first check which billing option you purchased, then verify that your remaining data looks right. Monthly subscription data resets each month on the activation date, not at the start of the calendar month. Data packages never expire, but usage still consumes data. “Never expires” doesn’t mean unlimited data or that every download is unmetered.
| Billing option | Price and data | What to check |
|---|---|---|
| Monthly subscription | ¥9.9 / 60GB | Confirm activation status and the monthly data reset date |
| Monthly subscription | ¥18 / 250GB | Make sure the plan tier matches your order |
| Monthly subscription | ¥28 / 500GB | Check your remaining data, not historical usage |
| Data package | ¥158 / 300GB | Never expires; data is consumed as you use it |
| Data package | ¥358 / 1000GB | Check the credited data against the selected tier |
| Data package | ¥658 / 3000GB | Monitor remaining data; it does not reset monthly |
Plans have no device limit, but keep an eye on your account’s data usage. When setting things up for the first time, verify the connection on one device before configuring others—it makes issues easier to pinpoint. See the plans page for full pricing. If your order and dashboard don’t match, contact support instead of trying to fix it with another payment.
Install a client: Choose the dashboard link for your device
After signing in, open the client download page and follow the instructions for Windows, macOS, iOS, Android, or Linux. Get downloads through the dashboard, and don’t substitute another app just because its name looks similar in search results. The dashboard handles iOS download eligibility and available options; follow the instructions shown after signing in.
The client is the app that makes the connection; the subscription provides the route configuration it reads. Installing the app doesn’t give you access to routes, and buying a plan in your browser won’t automatically set up a proxy on your device. Menu names such as “Profiles,” “Subscriptions,” or “Nodes” vary by client. Follow the matching dashboard guide rather than relying on screenshots from another app.
What to expect: The client opens normally, and you can find its profile or subscription settings. Common issues: The installer doesn’t match your operating system, the system blocks an app from an unverified source, or an older client is still running in the background. Check the platform instructions and download source first. Don’t disable all system protections just to proceed with installation. If your device is managed by your employer, check whether your organization allows you to install and use the client.
Desktop clients may offer both system proxy and TUN modes. A system proxy mainly affects apps that follow the operating system’s proxy settings. TUN mode uses a virtual network interface to route traffic covered by its configuration and usually requires additional permissions. Mobile devices typically create a tunnel through the system VPN settings. Seeing a VPN icon only means the related configuration is enabled; it doesn’t prove that a particular app is using the expected route.
Import your subscription: Check the configuration before connecting
A subscription link is used to retrieve route configuration. It isn’t a regular website address or your account password. Sign in to the dashboard to get your subscription. Use the import method provided for your client whenever possible. If you copy the link, check that it hasn’t picked up spaces, line breaks, or missing characters.
- Get the configuration: Find the subscription section in the dashboard and choose the configuration or import method that matches your client. You should get a subscription the client can read—not use the dashboard page address as a subscription link.
- Import and update: Use the client’s subscription import feature, then update the configuration. You should see a list of routes. If you get a parsing error, first check that the client supports the subscription format.
- Select the current configuration: Make sure the newly imported configuration is the one in use. You should see the relevant routes on the proxy group or route selection screen, rather than continuing to use an older configuration.
- Choose a route and connect: Select a route, grant the VPN or network permissions the system requests, and then connect. The client should show that it’s running without persistent authentication or connection errors.
Shadowsocks, VMess, Trojan, VLESS, Hysteria2, and TUIC are different proxy protocols or implementations, and client support varies. Don’t copy configuration fields from one protocol into another, and don’t assume S4VPN currently offers a particular type just because you see its name. Check the dashboard and client download instructions for available configurations.
Common issues: If the subscription downloads but no routes appear, the client may not support the configuration format. If routes appear but authentication fails, the configuration may be outdated or there may be an issue with your account status. Update the subscription and check your account before trying another client. Save any settings you need before reinstalling, so you don’t delete a working configuration.
Test your connection: Check your route, traffic rules, and DNS separately
Don’t rely on the client’s “Connected” status alone. First check that your internet works with the client off. Then connect and visit the IP lookup page to check the route used for the test request. If traffic rules send that page directly, the result may still show your local IP. Check the page’s routing rules before drawing conclusions; a single lookup can’t tell you whether every app is using the connection.
Rule-based mode chooses proxy or direct access according to conditions such as domain, address, or app. Global proxy mode typically routes traffic handled by the client through the proxy, but it doesn’t necessarily control every process on your device. For an initial test, temporarily use a mode that’s easier to verify, following the guide. Once you confirm the target site opens, switch back to your usual routing rules. Don’t leave rules you don’t understand layered into your configuration.
DNS translates domain names into addresses. A changed exit IP doesn’t mean DNS requests necessarily take the same route. Browser secure DNS, the system resolver, and the client’s DNS settings may each apply separately. When checking for DNS leaks, consider the client’s resolution policy, test results, and app settings together; a DNS provider’s name alone isn’t enough to draw a conclusion.
- ✅ The client is running normally, and the active configuration and selected route are clear.
- ✅ The target website loads fully, not just its page title.
- ✅ The exit lookup result matches the route used for that request.
- ✅ Your usual apps can complete a sign-in or other required task—you’ve tested more than just a browser.
- ✅ After restoring your usual routing rules, test again to make sure your changes haven’t altered the expected route.
Third-party websites may still restrict access based on account region, authorization, or their own risk controls. Being able to connect to a site doesn’t guarantee that its features will be available. S4VPN’s military-grade encryption doesn’t replace device security, website certificate checks, or account protection. If you see a certificate warning, don’t dismiss it just to open the page.
Common issues: Troubleshoot by narrowing down the cause
Nothing can access the internet: Disconnect the client first and check whether your regular connection works. Hotel and public Wi-Fi may require you to complete a browser-based sign-in first; switching to an international route usually won’t resolve a connection-layer issue. If internet access returns after disconnecting, check for leftover system proxy settings or another proxy app also routing traffic.
Websites work, but one app doesn’t: Check whether the app follows your system proxy, has its own proxy settings, or is set to bypass the proxy in your rules. Desktop apps and browsers may use different network routes. If you need to route more traffic through the client, configure TUN mode using the relevant guide. Don’t assume a failed app login means the route is at fault.
The connection drops when the screen locks: Android background limits and battery-saving settings can prevent the client from running continuously. Adjust your device settings to allow the necessary background activity. On other platforms, check sleep settings, network changes, and VPN configuration status. Avoid running multiple clients that compete for the system VPN interface, as this can cause connection states to keep changing.
Only one route has issues: Update the subscription and try another route. Note when the issue occurred, the route name, and the error message. Direct, transit, and IEPL dedicated routes describe different network arrangements, not a guaranteed speed ranking; they’re also different from proxy protocols. Don’t diagnose a problem based on a label without test results.
Troubleshooting approach: First check whether your account is active, then whether the client can read the configuration, and finally whether app traffic is taking the expected route. Change one setting at a time and record the result. It’s easier to find the cause this way than by switching routes, changing DNS, and reinstalling the client all at once.
Once you’re connected: Save your setup and support details
Once your usual apps work, note your client, connection mode, and selected route. When setting up another device, get a configuration suited to it from the dashboard instead of forwarding an old device’s entire configuration file. S4VPN covers 100+ countries / 190+ routes, but there’s no need to try them all. Stick with a route you’ve verified works for the app you need.
If the problem persists, include your operating system, client name, network environment, error message, and steps you’ve already tried in your support ticket. “I can sign in to the dashboard, but the subscription won’t update” is more helpful than “It doesn’t work.” Before sharing a screenshot, check that it doesn’t show your full subscription link, password, or private content.
S4VPN offers a 7-day no-questions-asked refund. For order or refund requests, use the support link in the dashboard and keep any relevant order records. For detailed instructions, see the guides and the user manual. You’re ready when your usual apps can reliably complete real tasks using the expected routing rules—not just when the client displays a particular status.
