This article addresses the common question, “What should I do if v2rayNG won’t connect?” Follow these checks in order, starting with the lowest-risk steps: check your browser and network first, then check DNS, node routes, and client settings. Avoid reinstalling the app or changing settings at random as a first step.
1. First determine whether the internet is down entirely or the proxy isn’t working
After opening v2rayNG, don’t rush to switch nodes repeatedly. Start with a basic check. Turn off v2rayNG and try visiting a domestic website in your browser. If it won’t load either, the issue may be with your mobile network, Wi-Fi, or carrier, rather than v2rayNG. If domestic websites work, turn v2rayNG back on and visit a website that requires a proxy.
- Test both your mobile network and Wi-Fi to rule out restrictions on your current network.
- Make sure your system clock is accurate. An incorrect time can cause TLS certificate verification to fail.
- On the v2rayNG home screen, check that a node is selected, then tap the start button in the lower-right corner.
- If it says “Connected” but webpages won’t load, continue by checking your browser and DNS.
2. Check your browser: rule out cache issues and proxy conflicts
Some users assume a node is faulty when the real cause is a browser cache issue, an extension, or a system proxy conflict. Try testing with your phone’s default browser or Chrome in Incognito mode. Don’t base your diagnosis on just one app. If you have ad blockers, proxy extensions, or network accelerator apps installed, temporarily disable them.
On Android, v2rayNG usually routes traffic through VPN mode. If another VPN, a campus network authentication client, or a phone manager’s network accelerator is also running, they may conflict. Make sure only one VPN-type app is active at a time. During testing, try visiting several websites rather than relying on just one.
3. Check DNS: a key step if the connection works but webpages won’t load
If v2rayNG shows that it’s connected but your browser keeps loading, a common cause is a DNS resolution issue. Open v2rayNG settings and check whether any unfamiliar DNS options are enabled. Most users should leave the defaults as they are, or try switching the routing mode to the common “bypass LAN and mainland China addresses” mode.
- Don’t configure multiple conflicting private DNS settings in your system, browser, and v2rayNG.
- If the “Private DNS” setting in Android is incorrect, DNS resolution may fail across all apps.
- After changing DNS settings, fully stop v2rayNG and then restart the connection.
If you imported subscription nodes, update the subscription first to avoid using outdated configurations. This site also compiles some free nodes for testing, but their stability depends on current route conditions, so it’s a good idea to have several alternatives ready.
4. Check routes and nodes: don’t focus on just one node
An unavailable node is the most common cause. You can long-press a node to view or test its latency, but low latency doesn’t guarantee that it will work properly. Try several nodes across different regions, protocols, and carrier networks. If a node worked yesterday but not today, the route may be temporarily down; the client itself isn’t necessarily at fault.
- Tap Update Subscription in the upper-right corner to make sure your node list is up to date.
- Try nodes in different regions, starting with nearby regions.
- Turn off advanced features such as “per-app proxy” and test with the default global mode first.
- Look for keywords in the logs, such as timeout, handshake, and connection refused, to determine whether the issue is a timeout, a handshake failure, or a server rejection.
If the logs show frequent timeouts, the current network likely can’t reach that route. A handshake failure may indicate that the node configuration has changed or the subscription hasn’t been updated. In this case, don’t change protocol parameters at random; reimporting the subscription is usually safer.
5. Low-risk recovery steps
We recommend trying these steps in order: restart v2rayNG, switch networks, update the subscription, switch nodes, turn off Private DNS, test with another browser, and restart your phone. If the issue persists, back up your configuration, then clear v2rayNG’s data and reimport the subscription. This minimizes the risk of accidentally deleting nodes that still work.
In summary, if v2rayNG won’t connect, first determine whether the problem is with your network, browser, DNS, or route. Checking each item in order is usually faster than repeatedly reinstalling the app and is less likely to disrupt settings that are already correct.
