This guide addresses the common question, “What should I do if v2rayNG won’t connect?” It walks through checks for your mobile network, node subscription, system permissions, and client settings to help you quickly determine whether the issue is your local environment, an unavailable node, or an incorrectly imported configuration.
1. First, check that your network environment is working
Many connection failures aren’t caused by v2rayNG itself, but by a network environment that doesn’t support proxy connections. Run through these basic checks before changing more advanced settings.
- Try switching networks: If you’re using Wi-Fi, switch to mobile data. If mobile data doesn’t work, try Wi-Fi instead. Some campus, workplace, and hotel networks restrict proxy connections.
- Turn off other proxies/VPNs: If you have another VPN, accelerator, or packet-capture tool running on your phone, it may be occupying the system VPN connection. Close them all first.
- Check the system time: A significant time discrepancy on Android can cause TLS connection failures. Turn on “Set time automatically” and “Set time zone automatically.”
- Check app permissions: In your system settings, allow v2rayNG to use the network. If your system restricts background activity to save power, remove that restriction for v2rayNG.
2. Check whether the node and subscription are working
If your network environment checks out, look at the node next. Free nodes often become unavailable due to congestion, expiration, or blocking. Free nodes provided by this site should also be updated regularly—don’t rely on a single node for too long.
- Open v2rayNG, long-press the current node, and select “Test current service connection” or a similar option to see if it returns a latency result.
- If you imported a subscription, tap the menu in the upper-right corner and select “Update subscription.” After updating, select a node again and reconnect.
- If you copied a vmess, vless, or trojan link manually, make sure you copied the entire link, including the protocol prefix and all trailing parameters.
- Try several regions or routes in the same subscription. Don’t conclude that the app is broken based on just one node.
3. Check your v2rayNG client settings
v2rayNG’s default settings usually work, so we don’t recommend changing routing or transport parameters without a good reason. Just check these few items:
- After selecting a node, tap the connect button in the lower-right corner and check that the VPN icon appears at the top of your phone screen.
- Go to “Settings” and make sure the local Socks/HTTP ports haven’t been changed to unusual values. If you’re not sure, restore the defaults.
- For the routing mode, start with “Bypass LAN and mainland China addresses” or the default rules to avoid misdiagnosing issues caused by switching between global and direct modes.
- If you see a configuration format error, delete the node and scan the QR code again or reimport it from your subscription.
4. How to interpret common errors
If a webpage won’t load at all but v2rayNG says it’s connected, the issue may be related to your browser cache, DNS, or routing rules. Try disconnecting and reconnecting, or restart your phone. If the log shows “timeout,” the node is likely unreachable or blocked by your current network. Messages containing “handshake,” “TLS,” or “certificate” usually point to node parameters, the system time, or certificate verification.
Here’s the recommended troubleshooting order: switch networks, update your subscription, try another node, and reinstall the client as a last resort. Don’t start by changing a lot of advanced settings. If all nodes fail on your phone but the same node works on another phone, the issue is more likely to be your system permissions, network environment, or a conflict with another VPN on your device.
5. Quick fix if you still can’t connect
Uninstall the old version of v2rayNG, install the latest version, and then reimport your subscription from a trusted source. After importing, test web access with a node that has normal latency, then try services such as video sites and app stores. Keep in mind that a successful connection doesn’t guarantee access to every website—different websites and networks may have different requirements for proxy routes. Following this checklist should help you identify most v2rayNG connection issues.
