Why Your VPN May Not Be Working on iPhone
VPN issues on iPhone typically arise from technical symptoms tied to specific causes, problems with VPN apps, or issues with your service subscription.
Common Symptoms and Causes
You may notice your VPN connection dropping or failing to establish. Error messages such as “VPN connection failed” or “Remote server is not responding” can appear.
Network settings often trigger these problems. If you have recently updated iOS, your VPN configuration may have reset.
Outdated VPN protocols like PPTP no longer function on newer iOS versions. You must switch to IKEv2 or OpenVPN for compatibility.
Your internet connection may cause VPN failures. Weak Wi-Fi signals or mobile data restrictions can prevent VPN connections.
Some public Wi-Fi networks in airports or hotels block VPN traffic.
Common technical causes include:
- Incorrect DNS settings
- Firewall blocking VPN ports
- Date and time settings not matching your actual location
- VPN permission settings disabled in iOS Settings
- Corrupted VPN configuration files
VPN Apps and Compatibility Issues
Some VPN apps do not function reliably on iPhone. Well-known providers often optimise their apps for iOS, but lesser-known providers may have buggy applications.
Your app version is crucial. Outdated apps frequently lose connection or fail to launch.
Certain VPN services require iOS 14 or higher for full functionality. If you use an older iOS version, some features may not work.
App updates can introduce new bugs.
Conflicts with other apps can disrupt your VPN. Security apps, ad blockers, or other VPNs installed on your device can interfere with each other.
Only one VPN can run at a time. Having multiple VPN apps active will cause connection failures.
Some VPN apps experience issues with specific iPhone models. Older devices may struggle with resource-intensive VPN protocols.
Subscription and Account Status
Your VPN will not work if your subscription has expired or your payment failed. VPN providers restrict access immediately when billing issues occur.
You should check your account status through the provider’s website or app dashboard.
Device limits can prevent connectivity. If you exceed the allowed number of simultaneous connections, your iPhone will not connect.
Account credentials must be current. Changed passwords or usernames that are not updated in the app will prevent authentication.
Some providers require separate credentials for manual configurations and app-based connections.
Regional restrictions can block accounts. If you purchased your subscription in one country but travel elsewhere, providers may flag this as suspicious activity and suspend access.

Essential Connection Checks
Your VPN must have a stable internet connection to function. Testing your basic connectivity and switching between connection types helps you identify the source of the problem.
Verify Internet Connection
Before troubleshooting your VPN, confirm that your iPhone has internet access. Open Safari and load a website without the VPN active.
If websites do not load, your internet connection is the issue. Move closer to your Wi-Fi router or check if other devices can connect to the network.
Check your connection status in Settings. Go to Settings > Wi-Fi and look for the tick next to your network name.
The Wi-Fi symbol at the top of your screen should show multiple bars for a strong signal.
Toggle Aeroplane Mode
Aeroplane mode disables all wireless connections on your iPhone. Turning it on and off forces your device to reconnect to networks and can fix temporary glitches.
Swipe down from the top-right corner of your screen to open Control Centre. Tap the aeroplane icon to enable aeroplane mode, wait 10 seconds, and tap it again to disable it.
Watch for the Wi-Fi and mobile data icons to reappear at the top of your screen. Once they return, try connecting to your VPN again.
This reset often resolves connection problems without further steps.
Test Wi-Fi Versus Mobile Data
Your VPN may work on one connection type but not another. Some UK networks or public Wi-Fi hotspots block VPN traffic, while mobile data typically allows it.
Connect to Wi-Fi and attempt to use your VPN. If it fails, disable Wi-Fi and try using mobile data instead.
If your VPN works on mobile data but not on certain Wi-Fi networks, the network is likely blocking your VPN protocol.
Update and Maintenance Solutions
Keeping your VPN app and iOS software up to date prevents many connection issues. Regularly restarting your devices and monitoring data limits also resolves common VPN problems.
Update VPN Apps and iOS Software
Outdated software causes most VPN failures on iPhones. VPN providers release updates to fix bugs and maintain compatibility with the latest iOS versions.
Check for VPN app updates in the App Store. Tap your profile icon and scroll to see available updates.
If your VPN app appears, tap Update next to it.
Update iOS by going to Settings > General > Software Update. If an update is available, tap Download and Install.
Install both VPN app and iOS updates within a few days of each other to avoid compatibility issues.
Restart Your iPhone and Router
Restarting your devices clears temporary glitches that block VPN connections.
Restart your iPhone by pressing and holding the power button and volume button until the power-off slider appears. Drag the slider, wait 30 seconds, then press the power button to turn it back on.
Restart your router by unplugging it from the power source. Wait one minute, then plug it back in.
Try connecting to your VPN after both devices restart.
Check for VPN App Data Limits
Some VPN services restrict performance or stability on lower-tier plans, which can lead to frequent disconnections on iPhone.
Open your VPN app and check your account dashboard or settings for data usage information.
If you have exceeded your limit, you must wait until next month or upgrade to a paid plan.
Configuration and Setting Adjustments
Incorrect settings or corrupted network configurations on your iPhone can cause VPN issues. Adjusting or resetting these settings often resolves connection problems.
Reset Network Settings
Resetting your network settings removes all saved Wi-Fi passwords, mobile data settings, and VPN configurations. This action returns your iPhone’s network setup to factory defaults.
To reset network settings, open the Settings app and navigate to General. Tap Transfer or Reset iPhone, then select Reset.
Choose Reset Network Settings. Enter your passcode and confirm.
Your iPhone will restart automatically. After it turns back on, reconnect to your Wi-Fi networks and reconfigure your VPN.
This fix resolves conflicts between your VPN and other network settings.
Remove and Re-add VPN Profiles
Corrupted VPN profiles can cause connection failures. Deleting and reinstalling these profiles creates a clean configuration.
Go to Settings and tap General. Select VPN & Device Management.
Tap the VPN profile you want to remove, then select Delete VPN.
After deletion, open your VPN app and follow the prompts to create a new profile. Enter your login credentials when prompted.
Some VPN providers require you to download a new configuration file from their website. Check your provider’s support documentation if needed.
Review VPN & Device Management
The VPN & Device Management section lists all active profiles and their status. Reviewing this area helps you identify configuration problems.
Open Settings, tap General, and select VPN & Device Management. Look for error messages or warning icons next to your VPN profile.
Profiles showing “Not Connected” or “Invalid” need attention.
Tap your VPN profile to view its details. Verify that the server address and authentication settings match your provider’s requirements.
Remove any old or unused profiles to prevent conflicts.
Advanced Troubleshooting Steps
If basic fixes do not resolve your VPN issues, you may need to adjust deeper iPhone settings or try a different app.
Switch VPN Protocols
VPN protocols determine how your device connects to the VPN server. Your current protocol might be blocked or incompatible with your network.
Open your VPN app and access settings or preferences. Find the protocol option, usually listed as OpenVPN, IKEv2, WireGuard, or L2TP.
Switch between available protocols one at a time.
IKEv2 works well on iPhones and handles network changes smoothly. WireGuard is newer and often faster.
If your VPN uses OpenVPN, try both TCP and UDP options.
Some UK networks block specific protocols, especially on public Wi-Fi. Testing different protocols helps you identify if your network is causing the problem.
Wait 10–15 seconds after switching protocols before attempting to connect.
Disable Private Wi-Fi Address
Your iPhone uses a random MAC address for each Wi-Fi network to protect your privacy. This feature can interfere with VPN connections on some networks.
Go to Settings > Wi-Fi and tap the information icon next to your connected network. Toggle off Private Wi-Fi Address.
Disconnect from the Wi-Fi network and reconnect. Your device will use its actual MAC address on that specific network.
Your VPN should now connect more reliably, though you will lose some privacy protection on that network.
Reinstall the VPN App or Switch Provider
Your VPN app may have corrupted files or bugs causing connection problems. Press and hold the VPN app icon on your home screen, then tap Remove App.
Download the app again from the App Store.
If reinstalling does not work, consider trying a different VPN provider. Some VPN apps experience more connection issues in the UK.
Check reviews from UK users before choosing a new provider. Many VPN services offer free trials or money-back guarantees, allowing you to test them risk-free.
When to Contact Support or Change Provider
Some VPN issues require expert help from your provider’s support team.
If basic fixes do not resolve the problem, consider switching to a more reliable service.
Contact VPN Support
Contact your VPN provider’s support team after you have tried standard troubleshooting steps without success.
Most providers offer live chat, email support, or ticket systems.
Use support when your VPN will not connect after multiple restart attempts.
Contact support if you receive specific error codes or messages.
Seek help when connection drops happen constantly despite correct settings.
Contact support if the app crashes repeatedly on your iPhone.
Report issues when features such as the kill switch or split tunnelling malfunction.
Provide detailed information when you contact VPN support.
Include your iPhone model, iOS version, and exact error messages.
Mention which troubleshooting steps you have already tried.
Many providers offer 24/7 support through their website or app.
Check if your VPN has a knowledge base or FAQ section, as you might find quick solutions there.
Consider Switching to a Reliable Provider
If problems persist after contacting support, your current VPN may not be suitable for UK users.
Some providers do not maintain strong UK server performance or fail to update their apps regularly.
Consistent connection failures across different networks indicate a need for a new provider.
Poor customer support response times also signal it is time to switch.
Limited UK server options and outdated iPhone apps with compatibility issues are warning signs.
Frequent service outages further suggest you should consider other options.
