- A three-step quick fix: switch servers, change protocol, restart VPN and device.
- If you’re in a restricted network work, school, or public Wi-Fi, you’ll likely need to use a protocol that supports obfuscated connections.
- Always verify by visiting a site that shows your IP and location, not just the VPN status indicator.

Quick fixes you can try immediately
- Step 1: Disconnect and reconnect the VPN. Sometimes the simplest fix works.
- Step 2: Switch servers. Some servers are overloaded or blocked by the network.
- Step 3: Change VPN protocol. Try WireGuard default vs OpenVPN TCP/UDP or IKEv2 if available.
- Step 4: Restart devices. A fresh boot can clear stuck network states.
- Step 5: Check your local network. If you’re on a public Wi-Fi, open a browser to a non-HTTPS site to test; some captive portals mess with connections.
- Step 6: Disable IPv6. In many cases, IPv6 leaks cause traffic to bypass the VPN.
- Step 7: Flush DNS. On Windows/macOS/iOS/Android, flushing DNS can resolve stale routes.
- Step 8: Temporarily disable firewall/antivirus. Some security suites block VPN traffic.
- Step 9: Reinstall Proton VPN app. A fresh install can fix corrupted configurations.
Platform-specific troubleshooting
Windows
- Verify connection status: Ensure Proton VPN shows connected and the traffic is routed through the VPN network.
- Change protocol: Open Proton VPN > Settings > Protocol, switch between WireGuard and OpenVPN TCP/UDP.
- DNS settings: Open Network and Internet settings > Change adapter options > Right-click Proton VPN adapter > Properties > Internet Protocol Version 4 TCP/IPv4 > Use the following DNS server addresses. Try 1.1.1.1 and 1.0.0.1 or 8.8.8.8/8.8.4.4 as a test.
- Firewall rules: Ensure Proton VPN is allowed through Windows Firewall. Add an inbound/outbound rule if needed.
- DNS leak test: After connected, run a DNS leak test to confirm DNS requests go through the VPN.
MacOS
- Protocol switch: Proton VPN on macOS supports different protocols; try switching from WireGuard to OpenVPN or vice versa.
- Kill switch: Ensure the app’s kill switch is enabled to prevent traffic leaks in case the VPN drops.
- Network utilities: Use Network Utility or Terminal commands to test routing netstat -rn and confirm tunnel IPs.
- Security/privacy settings: Check macOS firewall and privacy settings to ensure Proton VPN has necessary permissions.

- Start/stop the VPN: Fully disconnect, then reconnect. Mobile networks can swap routes during LTE/5G handoffs.
- Protocols: In Proton VPN app, try switching Protocol to WireGuard or OpenVPN if available to test stability.
- Battery optimization: Disable battery saver or optimizations for Proton VPN to prevent the app from being put to sleep during use.
- App permissions: Ensure VPN is allowed to create VPN service and that no other VPN apps are conflicting.
IOS
- Reconnect logic: Toggle VPN off, wait 5-10 seconds, then back on.
- Address caching: Clear Safari/cache to ensure the test pages aren’t cached in a way that misrepresents connectivity.
- Kill switch and app permissions: Confirm the kill switch is working and the app has required permissions.
- Reinstall: If issues persist, reinstall Proton VPN and re-allow necessary permissions.
DNS and leakage checks you can run
- Why DNS matters: VPNs encrypt traffic but DNS requests can reveal your activity if not routed through the VPN.
- Quick tests:
- DNS leak test site DNSLeakTest oriple: Run while connected to Proton VPN and observe if the DNS server shows a location different from your VPN.
- IP check test: Visit a site like whatismyipaddress.com to confirm the IP address is the VPN’s exit node.
- How to fix DNS leaks:
- Enable DNS over VPN within the Proton VPN settings if available.
- Manually set DNS servers within the OS to a trusted provider’s DNS e.g., Cloudflare 1.1.1.1 and ensure the VPN tunnel is set as the primary gateway.
Network and router considerations
- Router-level VPN: If you’re on a router that’s not passing Proton VPN traffic, you may need to enable VPN passthrough or configure a VPN on the router.
- NAT and firewall rules: Some networks block OpenVPN/WireGuard UDP traffic. If so, use obfuscated servers or a protocol that handles NAT traversal better.
- Public Wi-Fi traps: Some networks require captive portals; connect to a network with full access and then start Proton VPN for test.
- QoS and bandwidth: VPNs may throttle if the network has strict QoS policies. Try a less congested network.
Advanced fixes for persistent problems
- Check PC clock/time synchronization: A skewed clock can cause certificate validation issues in VPN clients.
- Update network drivers: Outdated VPN-related network drivers can cause drops; update drivers from your manufacturer’s site.
- Reset network settings: On Windows, run netsh winsock reset; on macOS, reset network settings through System Preferences after backing up settings.
- Check for VPN conflicts: Disable any other VPN clients or security apps that route or block VPN traffic.
- Inspect logs: Proton VPN logs can reveal connection errors like DNS leaks, certificate errors, or protocol handshake failures.

- Proton VPN strengths: Strong emphasis on privacy, transparent operations, good noise resistance against basic censors.
- Common pain points: In some networks, certain servers or protocols may be blocked or throttled.
- When to consider alternatives: If your network consistently blocks Proton VPN traffic, you might test NordVPN, ExpressVPN, or Surfshark to see if their obfuscation or server coverage yields a more stable connection.
Useful data and statistics
- VPN usage trends show that protocol choice can affect reliability up to 25-40% depending on network type and region.
- DNS leaks are detected in roughly 15-25% of VPN connections in consumer tests, underscoring the importance of DNS routing through the VPN.
- Obfuscated servers are most effective in networks with aggressive censors or strict firewall rules.
FAQs
Is Proton VPN still connected but not passing traffic?
Yes, this usually means a DNS or routing issue, or a protocol mismatch. Try switching servers, changing the protocol, and ensuring the kill switch is active.

DNS leaks don’t usually cause no internet by themselves, but they can reveal your real IP and potentially cause connectivity issues if DNS resolution fails inside the VPN tunnel.
What protocols should I use with Proton VPN?
WireGuard is fast and reliable, but some networks work better with OpenVPN UDP/TCP or IKEv2. Switch to test.
How can I verify DNS is routed through Proton VPN?
Run a DNS leak test while connected to Proton VPN. If the DNS server shows the VPN provider’s DNS, you’re good.
Does antivirus software affect VPNs?
Yes, some security suites block VPN traffic. Temporarily disable to test, then add Proton VPN as an exception. The Ultimate Guide to the Best VPN for Vodafone Users in 2026
