Users in mainland China often see the Binance App display "Network Error, please try again." This article troubleshoots the issue across three layers. Download entry: Binance official website, mobile Binance official App, and if you haven't installed the App on iOS, see the iOS installation tutorial.
1. Root Cause Classification
| Layer | Issue | Solution |
|---|---|---|
| DNS Layer | Resolving to wrong IP or polluted | Use DoH / DoT |
| Routing Layer | Carrier throttling/disconnects | Change carrier / network |
| Proxy Layer | Unstable VPN node | Change protocol / node |
| App Layer | WebSocket fails to connect | Clear cache and restart |
2. DNS Configuration
Global DoT on Android
Settings → Network & Internet → Advanced → Private DNS → Private DNS provider hostname → Enter 1dot1dot1dot1.cloudflare-dns.com or dns.google. Once enabled, all apps will use encrypted DNS.
iOS DNS Profile
Download the Cloudflare 1.1.1.1 app and install its DNS profile. Alternatively, manually change the DNS to 1.1.1.1 in your WiFi details.
Router Level
For home routers with firmware that supports DoH (like OpenWrt), a single configuration covers the whole house.
3. Proxy Selection
The Binance App uses WebSockets, so your choice of proxy protocol matters:
Recommended Protocols
- VLESS / VMess + WebSocket + TLS: Stable
- Shadowsocks 2022: Fast speed
- Trojan: Good obfuscation
Not Recommended
- Old SS (traffic is easily identified)
- HTTP proxies (do not support WebSockets)
- Free airport services (unstable nodes and risk of leakage)
Node Selection
- Preferred: Japan, Singapore, Hong Kong
- Secondary: US West, Taiwan
- Avoid: Overloaded nodes or unstable relays
4. App-Level Optimization
1. Clear Cache and Restart
Clearing the cache and logging in again recovers from most sporadic network errors.
2. Disable IPv6
Some carriers have unstable IPv6 routing. Disable IPv6 in your phone's APN / WiFi settings to force IPv4.
3. Do Not Run Multiple VPNs
Some users turn on two VPNs at the same time for "double insurance," but this actually causes conflicts. One stable VPN is enough.
4. Turn Off Traffic Acceleration
"Game acceleration" features from Tencent / 360 / security software are counterproductive for Binance WebSockets. Turn them off.
5. Identifying Network Environments
Home Broadband
Telecom / Unicom / Mobile have different policies. If it's frequently unstable, you can file a complaint with the carrier or switch.
Company WiFi
Companies might install SSL intermediate proxies, preventing Binance from connecting. It is recommended to use 4G or wait until you get home.
Public WiFi
Public WiFi is high-risk and unstable. Trading on it is strongly discouraged.
Mobile 4G/5G
The most stable option. However, it consumes data quickly.
6. Connection Log Analysis
Advanced users can use Wireshark to capture packets and see where the connection fails:
- TCP three-way handshake incomplete → Routing layer issue
- TLS handshake failed → Certificate / Man-in-the-middle
- WebSocket Upgrade failed → Proxy protocol issue
Regular users do not need to go this far; following the steps in this article is sufficient.
7. Long-Term Usage Suggestions
1. Primary + Backup Proxy
Any proxy might go down one day. It is recommended to have proxies from two different providers ready at all times.
2. Monitor Proxy Availability
Many proxy clients have a "latency test" feature. Run it regularly, and switch nodes if they are slow.
3. Follow Binance Announcements
Binance occasionally adjusts its CDNs / nodes, which will be posted on their announcements page.
4. Email as a Fallback
When there is a network error, the App cannot receive push notifications. Emails can still be received by domestic mailboxes (Gmail might be delayed), so rely on emails as a fallback for important changes.
FAQ
Q1: Do I need to log in again if I change the proxy protocol? No. The account session is on the server side; changing the connection protocol does not affect your login state.
Q2: What if cellular data is stable but expensive? Only turn on cellular data for critical operations, and switch back to WiFi normally.
Q3: Changed DNS but no effect? Restart your WiFi or toggle airplane mode. Some systems need to flush their cache.
Q4: When does it mean Binance is actually "down"? Check the official binance.com announcements on X. If there is widespread feedback from other users, it is indeed a platform-side issue.
