What stops VPNs from working over a mobile hotspot and why

• Carrier policy and throttling: Some carriers treat VPN traffic differently, especially on hotspots, to manage data use and network performance.
• NAT and firewall restrictions: The hotspot acts as a gateway with NAT, which can interfere with certain VPN handshakes.
• Protocol compatibility: Some VPN protocols like PPTP, L2TP are more easily blocked, while OpenVPN over UDP/TCP and WireGuard tend to fare better but can still be throttled.
• Device limitations: Some phones don’t allow full VPN passthrough on tethered connections, or they require specific settings to enable VPN on the hotspot network.
• DNS leaks and leaks of IP information: If DNS is not properly routed through the VPN, you may think the VPN isn’t working.

Top fixes in order of effectiveness

1. Verify hotspot and VPN basics

• Confirm hotspot is active and connected to your primary device.
• Verify the VPN app is up to date and the subscription is active.
• Reboot both the hotspot/source device and the device you’re using to connect phone, tablet, or computer.

2. Change VPN protocol and server

• If you’re using OpenVPN, try OpenVPN UDP for speed or TCP for reliability on poor connections.
• If you’re using WireGuard, switch to a different server or enable port-forwarding if your VPN supports it.
• Test several servers in different regions to identify if a specific server is the bottleneck.

3. Enable kill switch and DNS protection

• Turn on the VPN’s kill switch so all traffic is blocked if the VPN disconnects, preventing leaks.
• Enable DNS leak protection and consider using VPN-provided DNS servers to prevent DNS leaks.
• On some devices, set DNS to private or DoH DNS over HTTPS to the VPN’s DNS resolver.

4. Adjust hotspot settings on your phone

• Android: Look for Settings > Network & Internet > Hotspot & tethering > Personal Hotspot, then adjust APN and security. Disable “Allow VPN over Wi‑Fi” if the option exists and test again.
• iOS: Settings > Personal Hotspot, ensure VPN is allowed to pass through and test with a different VPN profile if available.
• If your device supports USB tethering, test with USB instead of Wi‑Fi to see if the issue is Wi‑Fi related.

5. Bypass double NAT issues

• Some hotspots create a double NAT scenario that complicates VPN connections. If possible, enable bridge mode or use a device that supports a simple NAT. Alternatively, connect directly to the VPN on the device hosting the hotspot and route traffic through the VPN.

6. Check firewall and antivirus settings

• Some firewall apps block VPN traffic on hotspot networks. Temporarily disable antivirus/firewall on the connected device and test again.
• Ensure VPN app is allowed through any device firewall rules.

7. Update device firmware and apps

• Update your phone’s OS to the latest version, because hotspot and VPN handling are often improved in newer builds.
• Update the VPN app to the latest version to receive the latest protocol improvements, bug fixes, and security patches.

8. Consider alternative VPN configurations

• Use split tunneling to route only certain apps through the VPN, reducing load and potential conflicts over the hotspot.
• Try a different VPN provider with a strong track record for mobile performance and robust obfuscated servers if you’re in a highly restrictive network.

9. Test with a different hotspot or SIM

• If you have another SIM or hotspot device, try that to determine whether the issue is carrier-specific or device-specific.
• Compare speeds and connectivity with and without VPN to gauge how much the hotspot impacts VPN performance.

10OS and hardware workarounds

• Some devices require a manual VPN profile rather than relying on the app. In this case, configure VPN in the OS system VPN to ensure all traffic is routed through the VPN tunnel.
