This article addresses the common question “What should I do if v2rayNG won’t connect?” We won’t cover setting up your own server. Instead, we’ll guide beginners through troubleshooting phone network issues, importing nodes, client settings, and system permissions to determine whether the problem is with your local network, an inactive node, or an incorrect configuration.
1. First, make sure the problem isn’t with your phone’s network
Many connection failures aren’t caused by v2rayNG, but by network restrictions, DNS issues, or system permissions. We recommend checking the following in order:
- Close v2rayNG and open a browser to visit a domestic website to confirm that your phone can access the internet normally.
- Switch between Wi-Fi and mobile data to test the connection. If Wi-Fi doesn’t work but mobile data does, the current Wi-Fi network may be restricted.
- Turn off battery saver and data saver to prevent the system from restricting v2rayNG’s background network access.
- Open your Android system settings and check whether v2rayNG has “Network access” and “Background activity” permissions. Some domestic phone brands block these by default.
- If you’ve used another VPN, accelerator, or packet capture tool, turn them all off before trying to connect again.
If you can’t access domestic websites either, fix your phone’s network first. If domestic sites work but the proxy doesn’t, continue troubleshooting the node and client.
2. Check whether the node is still working
A “Connected” status in v2rayNG doesn’t guarantee that you can access the internet, since a node may have expired, been blocked, changed addresses, or have an unavailable port. Here’s how to check:
- In the v2rayNG node list, long-press a node and select a latency test or connection test.
- Try 2–3 different nodes from the same subscription instead of repeatedly reconnecting to just one.
- If all nodes fail, update the subscription link to avoid using an old cached version.
- For vmess, vless, or trojan links copied manually, make sure no characters are missing.
If you’re using free nodes provided by this site, update to the latest subscription first, then test multiple nodes. Free nodes can be unstable due to the number of users or changes in network conditions, so when troubleshooting, consider the possibility that the node is unavailable or congested.
3. Check key v2rayNG client settings
After opening v2rayNG, tap the menu in the upper-right corner and check the following:
- Try turning “Enable local DNS” on or off. DNS settings can affect name resolution on some networks.
- Beginners should start with “Bypass mainland addresses” or the default routing rules. Avoid importing complex rules without a clear reason.
- If “Proxy only selected apps” is enabled, make sure apps such as your browser, Telegram, and YouTube are selected.
- When the system prompts you to allow a VPN connection, tap Allow. Otherwise, the client may appear to start without actually establishing a tunnel.
- Check that your phone’s date and time are correct. Incorrect settings can cause TLS certificate verification to fail.
To import a subscription, use “Subscription settings” in v2rayNG to add the link, then tap “Update subscription.” Don’t import a subscription URL as an individual node link, or it may fail to parse.
4. Check the logs for common errors
If v2rayNG fails to connect, open “Logs” to check for error messages. Beginners don’t need to understand every English message; just look for a few keywords: “timeout” usually points to a network issue, a blocked node, or high latency; “handshake,” “tls,” or “certificate” usually relates to encryption, TLS, or the device’s time; and “dns” means you should first try changing your DNS settings or network.
When you run into a problem, follow this order: switch networks → update the subscription → switch nodes → restart the client → check permissions → review the logs. Don’t start by uninstalling the app or changing advanced settings at random, as you might break a configuration that was working correctly.
5. What to do if you still can’t connect
If you’ve tried all the steps above, back up your subscription link before uninstalling. Then update v2rayNG to a newer version and import the subscription again. Some older versions have cores that are incompatible with newer configurations, which can prevent nodes using VLESS, Reality, or TLS from connecting properly. Finally, if the same node works in another client such as Clash or sing-box but not in v2rayNG, the issue is most likely with the client settings or version. If it doesn’t work in any client, the problem is more likely with the node or your current network.
