This article addresses the common question, “What should I do if v2rayNG won’t connect?” It focuses on troubleshooting node status, IP network connectivity, DNS resolution, browser settings, and client configuration. It’s intended for users who have already imported V2Ray/VLESS/VMess nodes but see timeouts on their phones, can connect but can’t open web pages, or can access only some websites.
1. First, check that the node and subscription are working
Connection failures often aren’t caused by a problem with your phone. The node may have expired, the subscription may be out of date, or the configuration may be invalid. Open v2rayNG and go to the server list. Long-press the current node, then select “Test real connection” or “Test latency.” If all nodes fail, update your subscription or copy the node link again from a reliable source. This site also lists free nodes that you can test, but their reliability can vary, so it’s a good idea to import several as backups.
- Open v2rayNG and tap “+” in the upper-right corner.
- Select “Import from clipboard” or “Subscription settings.”
- After importing, tap the menu in the upper-right corner and select “Update subscription.”
- Switch between nodes and test the latency and real connection for each one.
If only one node fails, that node is probably unavailable. If they all fail, continue with the network troubleshooting steps below.
2. Check your IP network: try both mobile data and Wi-Fi
v2rayNG depends on your current network environment. Some campus networks, office Wi-Fi, and public hotspots restrict proxy connections, causing persistent timeouts. First turn off the proxy and open a regular website to confirm that your phone can access the internet. Then test by switching between Wi-Fi and mobile data.
- Turn Airplane mode on and off to refresh your carrier IP address.
- Restart your router to rule out problems with the local network cache.
- Close other VPNs, network accelerators, and battery-saving apps.
- Make sure your phone’s system time is correct. An incorrect time can cause TLS connection failures.
If mobile data works but Wi-Fi doesn’t, the current Wi-Fi network is probably restricting the connection. If Wi-Fi works but mobile data doesn’t, your carrier’s network or APN settings may be the cause.
3. DNS settings can cause connections to work while websites remain inaccessible
Some users see v2rayNG show as connected, but still can’t open websites in their browser. In this case, check your DNS settings. In v2rayNG, open Settings and find the DNS options. It’s best to start with the default configuration rather than entering complex rules. If you’ve changed your DNS settings before, restore the defaults and reconnect.
Also check Android’s “Private DNS” setting. The path is generally Settings → Network & internet → Private DNS. If an unavailable address is entered, DNS lookups may fail. Temporarily set it to “Off” or “Automatic,” then try browsing again. Note that a DNS error won’t necessarily cause v2rayNG to show a connection failure, but it can prevent web pages from loading, images from opening, or apps from refreshing.
4. Browser settings can also lead to misleading results
If v2rayNG’s connection test succeeds but your browser isn’t working properly, try another browser, such as Chrome, Edge, or Firefox. Some domestic browsers have built-in security acceleration, DNS optimization, or data-saving modes that may bypass the system proxy. Try turning off features such as “Speed mode,” “Smart proxy,” “Ad blocking,” and “DNS acceleration.”
You can also clear your browser cache or test in incognito mode. If only one website won’t open, that doesn’t mean the node is completely unavailable. The issue may be related to the website’s policies, browser cache, or protocol compatibility.
5. Quick checklist for common settings
- Check whether the button in the lower-right corner of the v2rayNG home screen has been tapped to start the connection.
- For the routing mode, try “Bypass LAN and mainland China addresses” or use the default rules.
- Check whether the system has prompted you to grant VPN permission. You must tap Allow.
- Don’t change the node’s protocol, port, UUID, or transport settings without a reason.
- If per-app proxying is enabled, make sure your browser is selected.
In summary, if v2rayNG won’t connect, test the node first, then try another network, and then check your DNS and browser settings. Don’t start by repeatedly uninstalling the app. Following these steps in order will usually help you find the problem quickly. If it still fails, save the error log, try another node, or update to the latest version of v2rayNG and test again.
