What if v2rayN subscription updates fail?

Confirm the subscription URL is complete and reachable; retry on another network, or import a single share-link node first to verify the client itself works.

Android blocks installing v2rayNG (“Install unknown apps”) — what should I do?

In system settings, allow “Install unknown apps” for your file manager or browser, then tap the APK again to install.

Connected successfully but pages won’t load — what now?

Switch to a lower-latency node first; on Windows confirm system proxy is on; on Android confirm the VPN icon is present and permission is granted; if it still fails, update the subscription or check that local time is accurate.

v2rayN / v2rayNG / v2flyNG Tutorials

Full walkthrough of install, subscription import, connecting nodes, and common troubleshooting.

V2Ray client quick-start overview

Whether you use v2rayN（Windows / macOS / Linux）、v2rayNG(Android) or v2flyNG(Android · v2fly core), the full flow is: download & install → import subscription/nodes → pick a working node and connect → verify the network. Start with the shared steps below, then open the detailed guide for your platform.

1
Pick your OS and download a client

Different systems need different clients — the wrong one won’t install well or will feel broken:
- Desktop: download v2rayN(Win / macOS / Linux), install for your OS, then run
- Android (recommended for most people): download v2rayNG
- Android (when you need the v2fly core): download v2flyNG
On Android phones, prefer the arm64-v8a APK build.
2
Import a subscription URL or a single node

The client doesn’t ship with nodes — you need to import a config before connecting. Common ways:
- Subscription URL: import a full node set at once and update with one tap — best for daily use
- QR code: easiest on phones for quick adds
- Share link / clipboard: best for importing a single vmess://、vless://、trojan://、ss:// config
3
Test latency, connect, and verify it works

After importing, don’t tap nodes at random — test latency first (or check delay), then pick a reachable server. Once connected:
- Windows: confirm system proxy is on, then open a page in your browser
- Android: confirm the VPN icon appears in the status bar, then verify in a browser
- If pages won’t load, switch nodes first, then check whether the subscription updated successfully

Windows Complete v2rayN tutorial

v2rayN tutorial (detailed Windows guide)

This guide is for first-time v2rayN Windows users — covering download & extract, antivirus allowlisting, subscription import, node latency tests, system proxy / TUN switching, and how to troubleshoot failed connections.

1
Download v2rayN and extract it correctly

Open the v2rayN download page, prefer the Windows x64 build:
- After download you’ll get a zip — extract it with the system tool or 7-Zip / Bandizip
- Prefer extracting to D:\Tools\v2rayN or similar non-system-drive paths to reduce permission issues
- Do not copy only v2rayN.exe by itself—keep the entire folder
- Double-click to run v2rayN.exe; if it is blocked, add the folder to your antivirus trust list, then launch again
2
Import a subscription URL (recommended)

Subscriptions are ideal for managing many nodes. In v2rayN, open Subscription settings, paste the full subscription URL, save it, then run “Update subscription”:
- After a successful update, the main list shows a batch of nodes—names usually include a region or route label
- If the update fails, check whether the URL was truncated and whether your network can reach the subscription address
- Try another network first; if it still fails, import a single node link to verify the client works
Besides subscriptions, you can also import a single vmess://、vless://、trojan://、ss:// share link from the clipboard.
3
Test latency and pick a working node

After importing the node list, filter for connectivity first—don’t blindly connect to the first one:
- Use the client’s built-in latency test / real-delay test
- Prefer nodes with clearly lower latency and stable test results
- Skip nodes that time out or do not respond; refresh them later with a subscription update
- Try several nodes in the same region—speed and stability can vary a lot
4
Enable system proxy and start the connection

In v2rayN, set the proxy mode, then start the service:
- System proxy: easiest to start with—browsers and most apps follow it automatically; recommended for beginners
- TUN mode: takes over more thoroughly and covers apps that ignore system proxy, but may trigger security software prompts
- Make sure the current node is selected, then click Start (or the equivalent connect action)
- When the tray icon status changes, open a browser and visit a page to confirm it works
5
Everyday tips and troubleshooting
- Subscriptions can expire or change—update them manually on a regular basis
- If a connection fails, troubleshoot in order: switch node → update subscription → check system time → toggle system proxy / TUN
- On corporate or campus networks, try nodes that use a different transport (for example TLS / WebSocket routes)
- If the browser has a conflicting proxy extension, disable it before testing

Beginner tip:For the first run, start with “system proxy + a low-latency node.” Once it’s stable, enable TUN or adjust routing rules as needed—avoid changing too many settings at once.

Android Complete v2rayNG tutorial

v2rayNG user guide (detailed Android edition)

v2rayNG is one of the most popular V2Ray clients on Android and ships with the Xray core by default. This guide covers APK install, permissions, subscription/QR import, VPN authorization, per-app proxy, and connection troubleshooting.

1
Download the correct v2rayNG APK architecture

Go to the v2rayNG download pageand pick the package that matches your phone’s CPU architecture:
- arm64-v8a: best choice for most recent phones—download this first
- armeabi-v7a: for older 32-bit devices
- x86 / x86_64: mainly for emulators—usually skip this on regular phones
Before installing, allow the current app (file manager/browser) to install unknown apps in system settings, then tap the APK to install.
2
Import a subscription, QR code, or clipboard node

After opening v2rayNG, you can add configs in these ways:
- Subscription URL: paste the link in subscription settings and update—best for long-term use
- Scan QR code: fastest when someone shares a node QR code
- Import from clipboard: first copy a vmess:// / vless:// or similar link, then import it in one tap in the client
After a successful import, the main screen shows a node list. If the list is empty, the subscription likely failed to update or the URL is invalid.
3
Select a node, grant VPN access, and connect
- Tap the target node in the list (check latency or region first if you like)
- Tap Connect/Start; on first use, Android will ask for VPN permission—you must allow it
- After a successful connection, a key or VPN icon usually appears in the status bar
- Open a page in the system browser to confirm access works
If VPN permission is denied, the client cannot create a tunnel—“Connect” will appear to do nothing.
4
Enable per-app proxy when needed

Not every scenario needs a global proxy. v2rayNG supports per-app proxy (proxy by app):
- Proxy only listed apps: only browsers, messaging apps, and similar go through the proxy
- Bypass listed apps: bank and payment apps go direct; everything else uses the proxy
- This can cut battery use and reduce glitches in apps that misbehave when forced through a proxy
5
Update subscriptions and fix common issues
- When many nodes fail, update the subscription and retest—don’t keep reconnecting to old nodes
- Connected but no internet: switch nodes, check system time, and confirm the VPN icon is still present
- If a new version won’t install after an update: uninstall the old one first, or overwrite-install
- Aggressive battery savers may kill the background VPN—allow autostart / disable battery optimization in system settings

Signs of the wrong architecture:install fails, crashes, or shows an incompatible error. When unsure, download arm64-v8afirst; if that fails, try armeabi-v7a。

Android Complete v2flyNG tutorial

v2flyNG user guide (Android · v2fly core)

v2flyNG has nearly the same UI and workflow as v2rayNG; the key difference is the built-in v2fly（v2ray-core）. If you already know v2rayNG, migrating is easy—this guide focuses on the differences and a full getting-started flow.

1
Confirm whether you need v2flyNG
- Most Android users can simply use v2rayNG .
- Choose v2flyNG when you need the official v2fly core, want to stay aligned with the v2fly ecosystem, or your environment requires v2ray-core
- Then go to the v2flyNG download page, and likewise prefer arm64-v8a
2
Install and import configs

Installation matches v2rayNG: allow “Install unknown apps” → install the APK → open the app. Import options are the same:
- Batch-update nodes with a subscription URL
- Add quickly by scanning a QR code
- Import a single share link from the clipboard
Common supported protocols likewise include VMess, VLESS, Trojan, Shadowsocks, and more.
3
Connect, authorize, and verify
- Select a node, tap Connect, and grant VPN permission on first use
- Once the VPN icon appears, verify access in a browser
- If the same subscription works in v2rayNG but fails in v2flyNG, try another node or check whether that route depends on core-specific features
4
Per-app proxy and day-to-day upkeep

v2flyNG also supports per-app proxy. Suggested setup:
- Proxy messaging and browsing apps
- Keep banking, payments, maps/navigation direct as needed
- Update subscriptions regularly so you don’t keep reconnecting to dead nodes
- If a system update resets VPN permission, grant it again

vs v2rayNG—how to choose:Pick v2rayNG unless you have a special core requirement; choose v2flyNG only when you need the v2fly core. The two tutorials can be read side by side—the workflows are very similar.

Detailed Guides

Detailed guides by platform

Below are complete, ready-to-follow illustrated guides—easy to use step by step and friendly to search engines.

1. How do I use the v2rayN Windows client?

v2rayN is the mainstream graphical V2Ray client on Windows. First get the zip from this site’s Download Center and extract it fully, then run v2rayN.exe. If security software blocks the first launch, add the whole folder to the trust list and try again.

For setup, prefer a subscription URL: paste it in Subscription settings and update—nodes appear in the main list. Then run a latency test, pick a reachable route, enable system proxy, and connect. Browsers usually need no extra extension to verify. If some apps ignore system proxy, consider switching to TUN mode.

Common issues include: subscription update failures, all nodes red, or proxy on but pages won’t load. Suggested order: “switch node → update subscription → check system time and proxy toggle → look for conflicting browser proxy extensions.”

Open the step-by-step v2rayN tutorial

2. How do I use the v2rayNG Android client?

v2rayNG suits most Android users. When downloading, prefer the arm64-v8a APK, and allow installing unknown apps in system settings. After install, import nodes via subscription, QR scan, or clipboard; on first connect you must grant VPN permission, or no tunnel can be created.

After a successful connection, a VPN indicator appears in the status bar. To proxy only some apps, enable per-app proxy: for example, route your browser through the proxy while keeping banking and payment apps on a direct connection. That usually saves battery and fits everyday phone use better.

If you’re “connected but have no internet,” switch nodes and update the subscription; also check system time, whether battery optimization killed the background process, and whether the system revoked VPN permission.

3. What’s the difference between v2flyNG and v2rayNG, and how do I use it?

v2flyNG and v2rayNG are highly similar in UI and workflow; the main difference is the core: v2flyNG uses v2fly (v2ray-core), while v2rayNG defaults to Xray. Learning cost is low—if you know one, you can usually use the other.

The flow is the same: download the matching-architecture APK → import a subscription or QR code → grant VPN and connect → set per-app proxy as needed. Without a clear v2fly core requirement, v2rayNG is usually simpler; choose v2flyNG only when your environment or routes clearly depend on v2fly.

Open the step-by-step v2flyNG tutorial

4. What are subscriptions, nodes, and protocols?

A nodeis a single server config;a subscriptionis an update URL for a set of nodes—the client can sync the latest list automatically. Day to day, subscriptions are preferred so you don’t add nodes one by one. Single share links are better for quick tests.

Common protocols include VMess、VLESS、Trojan、Shadowsocks , and more. Beginners don’t need to master protocol details first: if the subscription or share link is valid, the client recognizes it and builds connectable nodes. What usually matters more is node quality, your local network, and whether the proxy mode is set correctly.

FAQ

Tutorial FAQ

Frequent questions about install, subscriptions, connections, and permissions.

Which tutorial should I follow for v2rayN, v2rayNG, or v2flyNG?

On desktop, use v2rayN (Win / macOS / Linux); most Android users should use v2rayNG; only when you need the v2fly core, use v2flyNG. All three follow “install → import → connect → verify.”

I only have a share link, not a subscription — can I still use it?

Yes. Copy the vmess://、vless://、trojan:// or ss:// link, then import it from the clipboard. Subscriptions are better for long-term bulk management.

What if v2rayN fails to update a subscription?

Check that the subscription URL is complete; retry on another network; confirm the local clock is accurate. If it still fails, import a single node first to verify the client can connect.

Android won’t install the APK (“Install unknown apps”) — what should I do?

Open system settings, allow “Install unknown apps” for the current file manager or browser, then tap the APK again.

Connected successfully, but pages still won’t load?

Switch to a low-latency node first; on Windows confirm system proxy is on; on Android confirm the VPN icon is still there. Also check for conflicting browser proxy extensions and calibrate system time.

What is per-app proxy? Should I enable it?

Per-app proxy lets you choose which apps use the proxy and which go direct. Enable it when you only want browsing/messaging proxied; keep global when every app should use the proxy.

What is the difference between system proxy and TUN mode?

System proxy is simple and works with most browsers and apps; TUN mode takes over more thoroughly for programs that ignore system proxy, but is more likely to be blocked by security software. Beginners should start with system proxy.
