YUYUVPN / SUPPORT

Help Center

Find answers based on where the problem occurs. Check your account and subscription first, then look at the client, server, and target app. Change one setting at a time and keep any error messages so you can tell whether a change helped.

For step-by-step instructions, see Guides →. For a full troubleshooting flow, see Troubleshooting →.

Account & Subscriptions

Create an account, get your configuration, or move to a new device. Your subscription URL contains access credentials, so protect it as carefully as your password when saving or sharing it.

Do I need an email address to create an account?

No email address is required. Create an account with a username and password. Keep them somewhere safe, and don’t confuse your account password with your client configuration. The user panel is for viewing subscriptions, orders, and support tickets; the client is for connecting to the network. If you can’t sign in, check your keyboard input, capitalization, and any spaces added when copying, then make sure you’re using the username saved when you created the account. Never send your full password in a support ticket or share your login details to troubleshoot an issue.

Where can I get the client and subscription?

Sign in to the user panel, open the downloads section, and get the client for your operating system. You can view your subscription details in the panel. Supported platforms include Windows / macOS / iOS / Android / Linux; check the panel for iOS download eligibility. Getting the client and obtaining an active subscription are separate steps. After installation, check your plan status in the account, then import the subscription as instructed in the panel. Your subscription URL contains account credentials, so save it on a trusted device. Don’t post it in public forums, shared documents, or screenshots.

How do I update my subscription, and what should I check afterward?

First, sign in to the panel and confirm your current subscription details. Then open the subscription or configuration management section in your client and update the relevant subscription. Button labels vary between clients, so follow the options shown in your app. After the update, check that the server list appears as expected, then select a server and test access. If the panel shows a new subscription URL, import it again using that URL. Once the new configuration works, you can remove the old one. Repeatedly clicking Update usually won’t reveal the cause of a problem. If it fails, note the client’s error message and continue with the connection troubleshooting section.

Do I need to buy again when I change devices?

There’s no limit on the number of devices connected at the same time, so changing devices alone doesn’t mean you need to buy again. Sign in to your existing account on the new device, download the client for its operating system, and import your account’s subscription. Device limits and plan data allowances are separate; check your remaining data and subscription status in the panel before use. If you’re giving away your old device, sign out and remove any saved subscription configuration so someone else can’t use it. If the new device won’t connect, check the import and system permissions first rather than assuming you’ve hit a device limit.

What should I do if my subscription URL may have been exposed?

Stop sharing the related screenshots or files, and check whether the panel offers an option to reset or replace your subscription. Follow the instructions shown in the panel. If you can’t find the option, open a support ticket explaining that your subscription may have been exposed and ask support what to do. Changing your account password and replacing your subscription URL are separate actions; don’t assume a password change will invalidate the old URL. Once the issue is addressed, update the configuration on your own devices and test the connection. Share only the error details needed to investigate, and redact credentials from the subscription URL and your account password.

Connections & Troubleshooting

Check your basic internet connection, client connection, and app access separately. “Connected” is the starting point for troubleshooting, not proof that you can access a website.

The client won’t connect at all. What should I check first?

Disconnect the client and check whether everyday websites load on your current network. If your basic internet connection isn’t working either, troubleshoot the local network first. If it is, check your subscription status in the panel, confirm the client configuration imported successfully, and allow any network permissions required by your operating system. Then update the subscription, test another server from the list, and note any error messages. Change one setting at a time so you can identify the cause; changing the server, proxy mode, and DNS all at once makes that harder. If the issue persists, include the checks you’ve already tried in a support ticket.

The client says it’s connected, but websites won’t load. What should I do?

A connected status only means the client has established a connection; it doesn’t confirm that browser requests are using the server as expected. Make sure the client is using the configuration you just imported, then check that the system proxy or related network routing feature is enabled as instructed by the client. Try different websites to see whether all sites fail or only a specific one, and check whether your browser has its own proxy settings or extensions. If the error mentions name resolution, check your DNS settings too. Keep your existing settings while troubleshooting, and don’t replace your configuration with a full set of parameters from an unknown source.

Why does my browser work, but a particular app won’t use the proxy?

Some apps don’t use the system proxy and may have their own proxy settings or connection rules. Fully quit the app, make sure the client is connected, then reopen it to rule out a reused connection. Check whether the app has network proxy settings and whether the client’s rules route the app’s domain through the intended server. If the client needs a network routing feature, check its instructions for permissions and compatibility rather than enabling every option at once. For work software or managed devices, check your organization’s usage policies first. Include the app name, operating system, and error message in your support ticket.

How can I troubleshoot a mobile connection that drops in the background?

Check whether the connection drops only after you lock the screen, switch apps, or change networks. If it works in the foreground but not in the background, review the operating system’s background activity, battery-saving, and network permissions for the client, and follow the client’s instructions. Switching between Wi-Fi and mobile data may require the connection to be re-established. Check the client’s status before testing the app again. Don’t turn off every system protection setting at once; after each change, test the same scenario to see whether it helps. In your support ticket, describe what you were doing when the connection dropped and whether it reconnects on its own when you bring the client back to the foreground.

What should I do about DNS errors or failed subscription updates?

First, identify whether the problem occurs while downloading the subscription or while browsing after connecting. If the subscription update fails, check whether the panel opens, whether the subscription URL is complete, and whether the client reports an incompatible format. If a webpage reports a name resolution error, check for conflicting DNS settings in the client and operating system, and temporarily rule out any browser-specific DNS settings. Keep your original configuration while making changes, and avoid switching between multiple DNS options at once. If you still can’t identify the cause, submit the exact error and say where the failure occurs. Redact the subscription URL and its credentials from screenshots.

Speed & Servers

Judge whether a server is suitable by how your target app performs. Keep the device and steps the same during tests to reduce variables.

Which regions do the servers cover, and how should I choose one?

Coverage includes 90+ countries / 170+ servers. The available options are listed in the panel and in the client after it updates. Choose a server based on the target service’s regional requirements, then compare how it performs on your current network instead of relying only on geographic distance. Hong Kong, Singapore, the United States, Japan, and the Netherlands can help you compare regions, but a region label doesn’t guarantee access to a particular website. Before switching, note the current server and how the target app performs, then repeat the same test on the new server. This makes it easier to distinguish server changes from app restrictions or local network fluctuations.

If things slow down at peak hours, should I switch servers or plans first?

Start by checking the server and your local network. Don’t assume slow speeds mean your plan is too limited. Pause large downloads on your devices, check whether other devices are using the network, then test another server against the same destination. If only a particular video or app is slow, check the service’s own status too. Note when the issue occurs, your network type, the server name, and what you’re seeing so you can compare results. Choose a plan based mainly on your data needs. Peak-hour performance depends on your local connection, the network route, and the destination service; changing plans isn’t a guaranteed fix for slowdowns.

Why do videos and AI tools still lag when speed tests look fine?

Speed tests, video streaming, and AI tools may connect to different servers in different ways, so one speed test can’t represent every app. Reproduce the issue using the same server and note whether pages load slowly, video buffers, or requests disconnect midway. Video performance can also depend on regional content availability, resolution, and platform policies. AI tools may be affected by account region, sign-in status, or long-lived connections. Avoid repeatedly switching regions while changing app settings at the same time. Keep the exact error message and test both web access and in-app actions to narrow down where the problem occurs.

What do IEPL, relay, and direct connection labels mean?

These labels describe a server route or access method; refer to the route details in the panel for their specific meaning. IEPL generally refers to dedicated-line access, relay means requests pass through an intermediate access node, and direct connection emphasizes a direct connection to the destination entry point. The labels themselves don’t replace real-world testing. Don’t assume every region offers the same route types or that one label guarantees faster speeds on every network. Choose a server that meets the target region’s requirements, then compare its performance on your current network. Available types are shown in the server labels. If you have questions, include the server name in a support ticket.

Is it normal for the same server to perform differently on different networks?

The route to a server can vary between networks. Wi-Fi signal, the connection environment, and the destination service can also affect performance. Keep the device, client configuration, and target app the same, and switch only the network to compare. If the issue occurs on just one network, check for access restrictions or congestion on that network first. Public and managed networks may have additional usage rules, so follow local requirements. When contacting support, you don’t need to share your exact location. Just provide the network type, whether switching networks changes the issue, and how the same server performs on another network.

Billing & Refunds

Monthly plans and data packages have different data rules. Keep the relevant order details handy when asking about payment, plan changes, or refunds.

How much do monthly plans and data packages cost?

Monthly plans: ¥9.9/month for 60GB · ¥18/month for 250GB · ¥28/month for 500GB. Data packages: ¥158 for 300GB · ¥358 for 1000GB · ¥658 for 3000GB. Data packages are valid until used and never expire. Monthly plans suit regular month-to-month use; data packages may work better if your usage varies. Choose based on your data needs, not just the total price. Monthly plan data resets each month on the date you activated the plan. Check the pricing page and confirm your selection in the panel before ordering. Don’t apply the data rules for one billing type to the other.

When does monthly plan data reset, and how is an upgrade calculated?

Data resets monthly on your activation date. If you upgrade mid-cycle, the price difference is prorated for the remaining days. Check your plan activation and data details in the panel; don’t assume every account resets on the first day of the calendar month. Before upgrading, review the adjustment shown in the panel rather than estimating the amount due from the full monthly price difference. If the displayed change doesn’t match your expectations, keep the order and plan details and ask support to review them in a ticket. Data packages remain valid until used and never expire, so monthly reset rules don’t apply to them.

Which payment methods are available, and what if my order doesn’t update after payment?

We accept Alipay / WeChat Pay / USDT. Choose a payment method in the user panel and follow the instructions on the order page. If the order status doesn’t change after payment, return to the orders section and check that the payment record matches the correct order. Don’t make repeated payments just because the status hasn’t updated yet. If you still can’t confirm the payment, open a support ticket with the order details, payment method, and a screenshot of the payment result. Include only information related to that transaction, redact other transactions, your account balance, and unrelated personal details, and never share your payment password.

What is the refund policy, and how do I request a refund?

14-day no-questions-asked refund policy. To request a refund, sign in to the account used for payment, open the support ticket section, and provide the order details that need attention. See the Terms of Service for the full policy. Troubleshooting information may help identify connection issues, but you don’t need to submit speed test results to request a refund. Keep order-related communication in your support ticket, and don’t post payment credentials publicly. If you can’t sign in to the panel, check the Contact page for guidance. Refund processing and arrival times depend on the support response and the payment provider.

What information should I include in a support ticket, and what should I leave out?

Say whether the issue concerns a subscription, connection, server, or order. Include your operating system, client name, what you were doing when the issue occurred, the server name, and the exact error message. For connection issues, you can also describe what happened after switching networks or servers; for order issues, include the relevant order details. Provide enough information to reproduce the issue, but don’t upload every log from your device. Check logs for sensitive information and redact it before sharing. Never send your login password, full subscription URL, or payment password. Add new findings to the same ticket instead of opening duplicate tickets so support can review the full context.
