Step‑By‑Step Instructions
1. Verify iOS Version and Update if Needed
Apple frequently releases patches that affect VPN stability. Go to Settings → General → Software Update and install any pending iOS version. After updating, reboot the device and test the VPN again. Many users report that the question “why does vpn keep turning off on iphone” disappears after a fresh OS install.
2. Check VPN Settings in iOS
Open Settings → VPN & Device Management. Make sure the toggle for “Connect On Demand” is enabled. This setting automatically re‑establishes the tunnel whenever network conditions change, which directly addresses the iPhone VPN disconnecting fix you’re looking for.
3. Examine the VPN Protocol
iOS supports IKEv2, IPSec, and WireGuard. IKEv2 is generally the most stable on cellular networks, while WireGuard can be faster on Wi‑Fi. Switch the protocol in your VPN app’s settings and observe whether the drop‑out frequency changes. This simple tweak often resolves “why does vpn keep turning off on iphone”.
4. Disable Low‑Power Mode
When Low‑Power Mode is active, iOS may suspend background network activity, causing the VPN to pause. Navigate to Settings → Battery and turn off Low‑Power Mode. This small change can be the decisive iPhone VPN disconnecting fix for many users.
5. Reset Network Settings
Corrupted network preferences can trigger intermittent VPN disconnects. Go to Settings → General → Reset → Reset Network Settings. After the device restarts, re‑enter your Wi‑Fi credentials and reconnect the VPN. This step is a proven solution for the “why does vpn keep turning off on iphone” mystery.
6. Review App‑Specific Permissions
Some VPN apps need permission to run in the background. Open Settings → [Your VPN App] and ensure “Background App Refresh” and “Location – Always” are turned on. Without these, iOS may close the VPN tunnel when you switch apps, leading to repeated disconnections.
7. Test on Different Networks
Connect to a trusted home Wi‑Fi, a public hotspot, and a cellular network. If the VPN stays alive on one network but drops on another, the issue is likely carrier‑level or hotspot‑level. Document the results, then contact the network provider with the data as part of your iPhone VPN disconnecting fix report.
8. Use a Reliable VPN Provider
Free or low‑quality services often lack robust keep‑alive mechanisms. For a professional solution, choose a provider with dedicated iOS apps and proven uptime. The link below offers a thorough review of top providers and explains why certain cheap options are not suitable for critical work.

9. Enable “Always On” VPN (Enterprise Feature)
If you manage devices through a Mobile Device Management (MDM) platform, you can enforce “Always On” VPN. This setting prevents any network traffic from leaving the device without encryption. It’s an enterprise‑grade iPhone VPN disconnecting fix that eliminates the “why does vpn keep turning off on iphone” problem for managed devices.
10. Final Verification
After applying all steps, monitor the VPN for at least 30 minutes while switching between Wi‑Fi, LTE, and Bluetooth accessories. If the connection remains stable, the troubleshooting cycle is complete. If not, consider the alternative methods outlined below.
Tips
Keep Your VPN App Updated
Developers regularly patch bugs that affect iOS background handling. Set your VPN app to update automatically via the App Store.
Use DNS Over HTTPS (DoH)
Enabling DoH in iOS Settings → Wi‑Fi → Your Network → Configure DNS → Automatic, or using a third‑party DNS app, can reduce latency spikes that sometimes force iOS to drop the VPN tunnel.
Leverage Cloudflare’s Learning Resources
For deeper understanding of how DNS and VPN interact, consult Cloudflare Learning. The articles explain why DNS leaks can cause VPN instability and how to prevent them.
Protect Your Privacy with the EFF
The Electronic Frontier Foundation (EFF) provides excellent guidance on selecting privacy‑focused VPNs. Visit EFF.org for independent reviews and best‑practice advice.
Alternative Methods
Use a Manual IKEv2 Configuration
If the built‑in app continues to drop, set up a manual IKEv2 profile in Settings → General → VPN → Add VPN Configuration. Enter the server address, remote ID, and authentication credentials provided by your VPN provider. This method bypasses the app’s background restrictions and can solve the “why does vpn keep turning off on iphone” issue for advanced users.
Switch to a Different VPN Protocol
Sometimes WireGuard works better on high‑speed 5G, while OpenVPN may be more resilient on older LTE networks. Experiment with each protocol in the app’s settings to discover which one offers the most stable connection for your locale.
Utilize a Site‑to‑Site VPN for Home Office
If you frequently connect from home to a corporate network, a site‑to‑site VPN might be more reliable than a client‑based solution. Read about the important characteristic of a site‑to‑site VPN in this article: Which statement describes an important characteristic of a site‑to‑site VPN?
Consider the Legacy Service Replacement
