There is more than one reason the Binance Official Site may fail to open. DNS hijacking, abnormal local Hosts file, network carrier blocking, corrupt browser cache, and regional access restrictions can all prevent binance.com from opening. Solutions in order of difficulty: first switch DNS, then clear browser cache, then try the app, and finally consider using officially announced backup domains. This article walks through how to troubleshoot step by step, how to use alternatives, and which approaches are compliant and which to avoid. If access already works, you can enter directly through the Binance Official Site. On mobile we recommend the Binance Official App. For iOS, see the iOS Install Guide.
First, Determine Which Layer Is Broken
Other Sites Also Don't Open
If sites other than Binance also generally fail to open, the issue is the local network or router. Restart the modem and router, or switch to mobile data — the issue usually disappears immediately.
Only Binance Doesn't Open
If only binance.com fails to open while other sites are normal, the problem is concentrated on DNS resolution or domain-level restrictions. Try switching DNS at this point.
App Works but Web Doesn't
If the app can log in and show markets but only the web fails, this means the app uses an independent API entry point with a different DNS resolution path than the web. In this case, just use the app directly and troubleshoot the web later.
Solution 1: Switch DNS
Public DNS List
When using the default carrier DNS, resolution may return wrong IPs. Switching to public DNS resolves most resolution issues. Common public DNS:
- Cloudflare: 1.1.1.1 and 1.0.0.1
- Google Public DNS: 8.8.8.8 and 8.8.4.4
- Quad9: 9.9.9.9
- Alibaba DNS: 223.5.5.5
Windows Switching Method
Control Panel → Network and Sharing Center → Change adapter settings → Right-click current connection → Properties → Select "Internet Protocol Version 4" → Properties → Use the following DNS server addresses, enter 1.1.1.1 and 1.0.0.1. After saving, run ipconfig /flushdns to refresh the DNS cache.
Mobile Switching Method
- Android: Long-press Wi-Fi name → Modify network → Advanced options → Change IP settings to static → Manually enter DNS.
- iOS: Settings → Wi-Fi → Tap the i button on the connected network → Configure DNS → Manual → Add Server.
DNS over HTTPS
Going further, enable DoH (DNS over HTTPS) to route encrypted DNS at the browser layer. Chrome Settings → Privacy and Security → Security → Use secure DNS, choose Cloudflare or Google. This way carriers cannot sniff DNS query content.
Solution 2: Clear Local Cache
Browser Cache
Press Ctrl+Shift+Delete to open the Clear Browsing Data dialog, choose "Last 7 days" or "All time," check Cookies and cache, and clear. Or use Incognito mode (Ctrl+Shift+N) to open binance.com once and see if it's a cache problem.
Check the Hosts File
On Windows the Hosts file is at C:\Windows\System32\drivers\etc\hosts. Open it with Notepad as administrator and check for any binance-related entries. If there are any, delete the entire line and save. Malware often adds phishing IPs to the Hosts file to hijack traffic, which is hard to detect without checking.
DNS Cache
On Windows command line, run ipconfig /flushdns; on macOS, run sudo dscacheutil -flushcache && sudo killall -HUP mDNSResponder.
Solution 3: Use Official Backup Domains
Backup Domain List
Backup domains announced officially by Binance include binance.info and binance.bz. Both point to Binance's official backup entry points, and account assets fully sync with the main site.
Usage Principle
Only use backup domains officially announced by Binance. Any other "Binance mirror site" or "Binance backup entry" may be phishing. The backup domain list can be found by searching "Access" at support.binance.com for the latest version.
The Official App Is a More Stable Choice
Compared to web DNS problems, the app has stronger anti-interference capability through mechanisms like domain pools, certificate pinning, and CDN acceleration. When the main site doesn't open, the app usually still works.
Troubleshooting Comparison Table
| Solution | Success Rate | Cost | Risk |
|---|---|---|---|
| Switch public DNS | High | Free | None |
| Clear cache / change browser | Medium | Free | None |
| Check Hosts file | Medium | Free | None |
| Official backup domain | High | Free | None, but confirm it's officially announced |
| Use the app | Highest | Free | Download must go through official channel |
| Network-layer tools | Varies by regional policy | Some paid | Compliance responsibility is yours |
Compliance Notes
Comply with Local Law
Users accessing overseas financial sites must confirm compliance with local law on their own. The DNS switching, cache clearing, and official app described in this article are all standard local network operations and do not involve bypassing restrictions. Any use of cross-border network tools must be evaluated for compliance risk on your own. Binance as an exchange does not itself encourage or oppose any specific regional policies.
KYC Address Must Be Real
Regardless of access method, information submitted during registration and KYC must match your real identity and place of residence. The risk control system cross-verifies across multiple dimensions. Once false information is identified, the account will be restricted or even frozen.
Common Misconceptions
Thinking Changing Domains "Unlocks" Things
Switching to Binance's official backup domain just changes the entry. Account policy and available features are identical. Some users think changing domains unlocks more coins or higher limits — this is impossible. Permissions fully follow the account's KYC level.
Trusting "Binance Internal Staff" Help
Anyone claiming to be "internal staff" who can help you "unlock" or "restore access" is a scammer. Binance official support only takes tickets at support.binance.com and does not proactively contact users through Telegram, WeChat, or QQ.
Installing Random Unfamiliar VPNs
Many unknown free VPNs on app stores sell user traffic to ad brokers or even do man-in-the-middle hijacking. Using such a VPN to access Binance amounts to handing your account and password directly to a third party.
Frequently Asked Questions
Mobile Data Can't Open It, but Wi-Fi Can — What's Going On?
This indicates DNS or access-point hijacking in the mobile carrier. Try switching the phone's APN, test with a SIM from another carrier, or enable DoH. Most of the time, switching to Wi-Fi and changing DNS resolves it.
Still Can't Open After Switching to 1.1.1.1?
Try 8.8.8.8 or 223.5.5.5. If all public DNS doesn't work, it's not a DNS-layer issue. Then check the Hosts file, firewall, and the "Web Protection" whitelist in antivirus software — sometimes antivirus blocks incorrectly.
Can I Keep Using the Backup Domain?
Backup domains are not the entry "recommended for daily use." Binance prefers users to use the main binance.com site or the app long-term. Backup domains are only a transitional fallback when main-site access is abnormal.
What If the App Doesn't Open?
Try the following order: turn off Wi-Fi and switch to data, clear app cache, uninstall and reinstall the latest version, and contact support.binance.com with a ticket. The vast majority of app connection issues are caused by local network or an outdated version.
Web Page Opens but the Login Page Is Blank
Usually a browser extension or ad blocker plugin is blocking scripts on the login page. Temporarily disable all extensions, or test in Incognito mode. Once you confirm which extension conflicts, add it to the whitelist.
