FAQ & Troubleshooting

How do I sign up and create an account?

Visit nextunnel.com and click "Sign Up". Enter your email address and choose a password. After confirming your email, you can immediately purchase a plan and receive your VPN credentials.

How do I pay with crypto (NowPayments)?

On the checkout page, select "Pay with Crypto". You will be redirected to NowPayments where you can pay using Bitcoin, Ethereum, USDT, and 50+ other currencies. Once your transaction is confirmed on-chain (usually within 10–30 minutes), your subscription is activated automatically.

How do I connect on Windows, Mac, Linux, and Android?

After purchasing a plan, open your dashboard and go to "Devices". Add a device and download the configuration file or copy the connection link. NexTunnel uses the VLESS+Reality protocol, which is supported by v2rayN (Windows), v2rayU (Mac), Nekoray (Linux), and v2rayNG (Android). Detailed setup guides are available in the Guides section.

What should I do if the VPN is not connecting?

First, check your internet connection without the VPN. Then verify your device's configuration is up to date (re-download from the dashboard if needed). Try switching to a different protocol — NexTunnel offers Standard, CDN (WebSocket), and Hysteria2 links. If problems persist, check the Status page for server issues.

How do I use the referral program?

Go to your dashboard and find your unique referral link in the "Referrals" section. Share it with friends. When they sign up through your link, both you and your friend receive a free trial credit. Commissions are credited to your account automatically.

Is NexTunnel safe to use in Russia and Iran?

Yes. NexTunnel uses the VLESS+Reality protocol, which is specifically designed to be undetectable by deep packet inspection (DPI) systems used in Russia, Iran, and other restricted regions. It mimics normal HTTPS traffic on port 443. We also offer CDN and Hysteria2 connection modes for additional resilience.

What protocols does NexTunnel use?

NexTunnel supports four connection types: Standard (VLESS+Reality on port 443 — best for most users), Restricted (alternative port and SNI for stricter networks), CDN (VLESS over WebSocket via Cloudflare — most censorship-resistant), and Hysteria2 (UDP-based, best for high latency or lossy connections). All types are available in your dashboard.

How do I cancel or request a refund?

To cancel, go to Dashboard → Subscription and click "Cancel Subscription". Your access continues until the end of the paid period. For refunds, contact support within 3 days of purchase. Crypto payments are non-refundable due to blockchain transaction costs.

Is VPN legal in Iran?

VPN legality varies globally. In many countries including Iran, Russia, and China, using unauthorized VPNs is restricted, though enforcement and penalties differ. NexTunnel operates without logging your activity, meaning we cannot be forced to share your browsing data. Always review your local laws and use VPN responsibly for legitimate privacy purposes.

Can VPN bypass the Great Firewall of China?

Yes, NexTunnel bypasses China's GFW using VLESS+Reality, which disguises traffic as regular HTTPS and evades DPI detection. Hysteria2 over UDP offers an alternative when TCP filtering intensifies. However, no VPN guarantees 100% unblockable access — the firewall continuously evolves. NexTunnel adjusts protocols regularly to maintain reliability.

Which VPN works during internet shutdowns?

During complete shutdowns, no VPN works if your ISP cuts all traffic. However, during partial blockades that target VPN protocols, NexTunnel's VLESS+Reality survives because it mimics HTTPS. Our CDN mode routes through Cloudflare IPs, which are harder to block. Hysteria2 over UDP also bypasses TCP-only throttling imposed during filtering waves.

How does VLESS Reality differ from V2Ray?

VLESS is a protocol while V2Ray is a platform that runs multiple protocols. VLESS+Reality is V2Ray's censorship-resistant mode that disguises traffic as TLS 1.3. V2Ray without Reality is detectable by DPI because it lacks encryption camouflage. NexTunnel uses VLESS+Reality specifically for undetectability in restricted regions.

What is anti-DPI VPN technology?

Anti-DPI VPNs bypass deep packet inspection by hiding encryption signatures. Instead of using obvious VPN protocols, they mimic legitimate traffic like HTTPS or TLS. NexTunnel's VLESS+Reality makes VPN packets indistinguishable from normal website browsing. This beats DPI filters that scan packet patterns to identify and block VPN traffic.

Can I pay for VPN with crypto from Iran?

Yes. NexTunnel accepts Bitcoin, Ethereum, USDT, and 50+ cryptocurrencies via NowPayments. Crypto payments are processed on-chain without KYC requirements, protecting your identity. No banking infrastructure or international credit card needed — perfect for users in sanctioned regions like Iran. Payment confirmation typically takes 10–30 minutes.

Why does my VPN disconnect every few minutes?

Frequent disconnections usually mean your server is overloaded or your ISP is throttling the connection. Switch to a different server or protocol in your NexTunnel dashboard. CDN and Hysteria2 modes are more resilient against throttling. If problems persist, your ISP may be blocking specific IP ranges — contact support to test alternative server assignments.

What is the difference between AmneziaWG and WireGuard?

WireGuard is a fast but easily detectable VPN protocol due to its fixed packet size and fingerprint. AmneziaWG adds obfuscation and packet padding to hide WireGuard's signature, making it useful in censored networks. NexTunnel prioritizes VLESS+Reality for superior stealth, but AmneziaWG is available on specific servers for users preferring WireGuard's speed with DPI resistance.

Is NexTunnel logging my activity?

No. NexTunnel operates on a strict no-logging policy — we do not record your browsing history, IP addresses, or connection timestamps. Our servers are designed to minimize data retention. Even if compelled by law, we cannot provide user activity logs because they are not stored. Your privacy is protected by architecture, not just policy.

How fast is Hysteria2 compared to OpenVPN?

Hysteria2 is significantly faster than OpenVPN on poor or high-latency connections because it uses UDP and has lower overhead. OpenVPN over TCP is slower due to packet acknowledgment delays, especially on lossy networks. Hysteria2 achieves near-native speeds even with 5% packet loss. For streaming or gaming in restricted regions, Hysteria2 outperforms OpenVPN.

VPN connection fails

1. Check that your internet connection works without the VPN.
2. Re-download your configuration from the dashboard — credentials may have rotated.
3. Try a different connection type: CDN or Hysteria2 are more resilient in restricted networks.
4. Check the Status page (nextunnel.com/status) for any server incidents.
5. Temporarily disable your firewall or antivirus and retry.

Slow VPN speeds

1. Switch to the CDN or Hysteria2 connection type in your dashboard.
2. Close other bandwidth-heavy applications while connected.
3. Try reconnecting — your device may be routed to a different, less-loaded server.
4. Run a speed test on your base connection to rule out local issues.

Payment issues

1. For card payments via Stripe: ensure your card supports international transactions and 3D Secure authentication.
2. For crypto payments via NowPayments: wait at least 30 minutes for blockchain confirmation. Do not close the payment page until you see a confirmation.
3. If your payment was charged but the subscription was not activated, contact support with your payment reference number.
