This article addresses the common issue of “What should I do if v2rayNG won’t connect?” and focuses on troubleshooting from several angles: node status, mobile network, IP, DNS, and browser environment. You don’t need to understand server-side configuration—just follow the steps to check, and in most cases you’ll be able to identify problems such as failure to connect, being unable to open webpages after connecting, or abnormal behavior on certain websites.
1. First, make sure the node and import method are correct
When v2rayNG fails to connect, the most common cause is usually not that the app is broken, but that the node has expired, the subscription has not been updated, or the copied format is incomplete. First open v2rayNG, long-press the current node, and confirm that information such as the address, port, UUID, and transport protocol is not blank. If you are using a subscription link, it is recommended to manually update the subscription first.
- Open v2rayNG and tap the “+” in the top right corner or “Subscription settings” in the menu.
- Make sure there are no extra spaces in the subscription address, save it, and then tap “Update subscription.”
- Select a node and tap the circular button in the bottom right corner to start the connection.
- Open your phone’s browser and visit a commonly used website to test; don’t rely only on whether the app icon changes color.
If this site’s free node page has an available subscription or single-node link, you can also import it temporarily for comparison testing. If the new node connects successfully, the original node has most likely expired or been restricted.
2. Check your phone’s network, IP, and system proxy status
If none of the nodes can connect, first switch network environments. For example, switch from Wi-Fi to mobile data, or restart the router and try again. Some public Wi-Fi networks, campus networks, and corporate networks may restrict proxy traffic, causing v2rayNG to time out continuously.
After connecting, it is recommended to search for “IP lookup” and confirm whether the displayed outbound IP has changed. If v2rayNG shows that it is connected but the IP is still your local network’s IP, the system VPN permission may not have been established properly. In this case, close v2rayNG, go to the VPN page in your phone’s settings, delete the old v2rayNG VPN configuration, and then authorize the connection again.
- timeout: usually means the node is unreachable, the network is blocking it, or the port is restricted.
- connection refused: the node’s port may be closed, or the configuration may not match.
- Connected but webpages won’t open: focus on checking DNS, routing mode, and browser proxy settings.
3. DNS settings can affect whether webpages open
Many users overlook DNS. A typical symptom is that v2rayNG shows the connection as successful, Telegram or some apps work, but the browser cannot open websites, or shows DNS_PROBE-related errors. You can find DNS-related options in v2rayNG settings and use the app’s default DNS, or try switching to a common public DNS. Do not set DNS in multiple accelerators or proxy tools at the same time, as this can easily cause conflicts.
In addition, Android’s “Private DNS” may also affect resolution. Go to system settings and search for “Private DNS.” If a domain name is currently entered there, try changing it to “Automatic” or “Off” first, then reconnect v2rayNG and test again.
4. The browser environment can also lead to misjudgment
Sometimes the issue is not that v2rayNG has failed, but that browser cache, extensions, or proxy settings are causing the problem. It is recommended to test in incognito mode or switch to a different browser. If you have installed browser extensions with proxy features, disable them first. On Android, Chrome, Edge, and Firefox usually follow the system VPN, but some domestic browsers may have their own acceleration, DNS, or security filtering features.
When troubleshooting, keep the environment simple: only enable v2rayNG and test with a single browser; do not run other VPNs, accelerators, or packet-capture tools at the same time. This makes it easier to determine where the problem is coming from.
5. Quick troubleshooting order summary
- Update the subscription and test with 2–3 different nodes.
- Switch between Wi-Fi and mobile data to rule out network restrictions.
- Check system VPN authorization; if necessary, delete the old configuration and reconnect.
- Turn off Private DNS and test using the default DNS.
- Switch browsers or use incognito mode, then clear the cache and try again.
If the above steps still fail, you can check the logs in v2rayNG, note down the error keywords, and continue troubleshooting based on prompts such as timeout, TLS, DNS, refused, and so on. For ordinary users, it is usually more effective to start with the four areas of nodes, network, DNS, and browser than to keep reinstalling the app.
