This article addresses the common question, “What should I do if v2rayNG won’t connect?” It’s designed to help beginners troubleshoot step by step: check your phone’s network, node configuration, subscription updates, and app settings to quickly determine whether the issue lies with your local network, an inactive node, or an incorrect client configuration.
1. First, check that your phone’s network is working
Many connection failures aren’t caused by a problem with v2rayNG itself, but by restrictions on the current network. Before repeatedly reinstalling the app, work through these checks in order.
- Close v2rayNG and use your browser to open a domestic website to confirm that your phone can access the internet.
- Switch between Wi-Fi and mobile data and test again. Some public Wi-Fi networks, campus networks, and company networks restrict proxy connections.
- Turn off battery saver and data saver to prevent the system from disconnecting the VPN in the background.
- If you’re using public Wi-Fi, complete the web login authentication first, then open v2rayNG.
If domestic websites won’t load either, the problem is with your phone or carrier network. If they load normally but the proxy doesn’t work, continue by checking the node and client.
2. Check whether the node is working
The most common reasons v2rayNG won’t connect are an inactive node, excessive latency, or an incorrect configuration. Open v2rayNG, long-press the current node, and select “Test current configuration’s real connection” or a similar test option. A timeout, TLS error, or handshake failure usually means the node is unavailable or your network can’t reach it.
- Try switching to another node in the same subscription.
- If you imported a link manually, make sure it includes a prefix such as vmess, vless, or trojan.
- If the node is from a subscription, tap the menu in the top-right corner to update it. Don’t rely on an old cached version for too long.
- We recommend keeping several backup options from the free nodes provided on this site. Free nodes may become temporarily unavailable as the number of users or network conditions change.
Avoid changing fields such as the address, port, UUID, encryption method, or transport protocol at random. If you’re new to this, avoid editing the configuration manually once it’s been imported, so you don’t accidentally break it.
3. Check v2rayNG’s basic settings
If the node is working but the connection still fails, check the client settings. First, make sure you’ve selected the intended node, then tap the Connect button in the bottom-right corner. A VPN icon should appear at the top of your phone’s screen. The first time you connect, the system will ask for VPN permission; select Allow.
On the Settings page, beginners should stick with the default configuration, especially when it comes to complex routing rules. Check these items in particular: for Routing mode, start with “Bypass LAN and mainland China addresses.” If you’ve changed the DNS settings, restore the defaults. If “Proxy only mode” or other advanced features are enabled, turn them off and try again.
Some domestic Android systems also restrict background activity. In your phone’s system settings, allow v2rayNG to run in the background and start automatically, and exclude it from battery optimization to prevent the connection from dropping when you lock the screen.
4. Diagnose the problem based on the symptoms
- Stuck on “Connecting”: usually caused by a node timeout, network blocking, or an expired subscription.
- Connected, but web pages won’t load: check routing and DNS, or test with another browser.
- Only some websites won’t load: this may be a routing rules issue. Switch to global mode to test.
- Subscription update fails: check that the subscription link is complete and that your current network can access the subscription URL.
When troubleshooting, change one setting at a time and test immediately afterward. This makes it easier to pinpoint the cause. Don’t change the node, DNS, and routing mode all at once, or it will be difficult to tell which change made a difference.
5. Recommended troubleshooting steps for beginners
- Confirm that your phone can access the internet normally.
- Switch between Wi-Fi and mobile data, then try again.
- Update your subscription and test 2–3 nodes.
- Restore v2rayNG’s default settings and reimport the node.
- Check VPN permission, battery optimization, and background permissions in your system settings.
In summary, v2rayNG connection failures usually come down to four causes: network restrictions, an inactive node, an expired subscription, or incorrect client settings. Following this guide in order should help beginners identify the likely cause. If none of several nodes work, consider switching subscription providers or trying again later.
