Proton VPN tends to reconnect automatically on most servers, but the pattern short drops vs long outages varies by protocol and server location.
Some users report better stability with WireGuard-based protocol on clean networks; OpenVPN may be more stable on punishment-prone networks but slower.
If you’ve got a flaky router, you’ll want to investigate local network settings in addition to Proton VPN tweaks.

Top fixes in order of impact

Check Proton VPN service status and regional outages

Visit Proton VPN status pages or third-party uptime trackers.
If there’s a known outage, you’ll want to wait or switch to a less impacted region.

Update Proton VPN app and device OS

Ensure you’re running the latest version of Proton VPN on your device.
Update your OS to receive the latest security and performance fixes.
Why it helps: updates fix bugs that can cause disconnects and improve protocol handling.

Switch servers and choose a different region

Disconnect from the current server and pick one with lighter load.
If possible, choose a server geographically closer to you or in a region with better routing for your traffic.
Pro tip: sometimes a simple hop to a neighboring country reduces latency spikes.

Change the VPN protocol

Try WireGuard first for speed and stability; switch to OpenVPN UDP or TCP if issues persist.
If you’re on a mobile network, UDP usually performs better, but TCP can be more stable in congested networks.

Disable or adjust the Kill Switch and Network Lock

If Network Lock kill switch is enabled and you’re seeing frequent drops, try a momentary disable to test stability.
Re-enable after confirming the connection is stable to maintain protection if it drops unexpectedly.

Check DNS and IP leaks

Use Proton VPN’s built-in DNS or switch to a trusted DNS provider during testing e.g., 1.1.1.1 or Google DNS.
Run a DNS leak test online to confirm traffic isn’t leaking outside the VPN tunnel after reconnects.

Test on a different device or network

If you have another device handy, test Proton VPN there to determine if the issue is device-specific.
Try a different Wi‑Fi network or mobile data to see if the problem is network-related.

Router and firewall considerations

If you’re on a home router, ensure UPnP is enabled or that port forwarding is not blocking VPN traffic.
Some routers have built-in firewalls that block VPN traffic; consult your router’s docs to adjust settings.
If you’re on a corporate or campus network, VPN traffic can be throttled or blocked; use a personal hotspot to test.

Disable conflicting software

Temporarily disable antivirus or firewall software to test if it’s interfering with Proton VPN.
If the problem goes away, re-enable protection and add Proton VPN as an exception.

Reinstall Proton VPN

If all else fails, back up any needed configs or settings, uninstall Proton VPN, reboot, reinstall, and log in anew.
A clean install can clear corrupted config files that cause disconnects.

In-depth troubleshooting steps by scenario

Scenario A: You see a short drop every few minutes
- Likely cause: server overload or protocol mismatch.
- Fix: switch server; try WireGuard; test on another device to confirm if the issue is server-side.
Scenario B: You can’t connect at all after a drop
- Likely cause: DNS or firewall interference.
- Fix: reset network settings, flush DNS, switch DNS provider, disable kill switch temporarily.
Scenario C: Connection is unstable on mobile data Can governments actually track your vpn usage lets find out
- Likely cause: carrier throttling or poor signal.
- Fix: switch to a different protocol, use a nearby server, or test with a stronger signal.
Scenario D: Works on Wi‑Fi but not on cellular
- Likely cause: carrier blocks or throttling for VPN.
- Fix: use WireGuard with a different port, or connect via a private hotspot.

Data, statistics, and authority

VPN usage trends show DoS attacks and outages fluctuate with regional events, so staying on top of status pages matters.
WireGuard tends to outperform OpenVPN in latency tests on mobile networks, while OpenVPN can be more robust on strict networks.
Real-world reports indicate that switching servers and protocols yields spikes in success rates for reconnects within minutes.

Pro tips for long-term stability

Schedule routine app updates and OS updates to reduce the chance of compatibility issues.
Keep a small set of favorite servers that you know are stable for your location.
Use a wired connection when testing VPN performance on desktops to reduce wireless variability.
Consider a dedicated router with VPN support for stable home usage.

A quick-start cheat sheet

Step 1: Check Proton VPN status. Step 2: Update app and OS. Step 3: Change servers. Step 4: Change protocol WireGuard first. Step 5: Test DNS. Step 6: Toggle kill switch. Step 7: Check firewall/router. Step 8: Test on another device/network. Step 9: Reinstall if needed.

What I did and what you can try today

I started by checking the Proton VPN status and updating the app.
Swapped from OpenVPN to WireGuard, and ping stability improved noticeably.
I switched servers to a nearby region and saw a decrease in latency and fewer disconnects.
I disabled the kill switch for a quick test, then re-enabled it after confirming stable connections.
I tested DNS with Proton’s DNS and then with Cloudflare DNS to ensure no leaks.

You can test and repeat:

Run a speed test before and after changes to quantify improvements.
Use a 2–3 server rotation to identify which ones are consistently reliable.
Keep a log of changes and outcomes to avoid repeating ineffective steps.

Frequently Asked Questions Brave vpn omdome ar det vart pengarna for dig

Table of Contents

How can I tell if Proton VPN is really disconnecting or just temporarily failing to reconnect?

Often you’ll see a brief gap in the VPN status or a moment where traffic routes through the regular network. If the app shows a disconnected state for more than a few seconds, it’s a true disconnect. Use ping tests and DNS checks to confirm traffic isn’t leaking.

Which Proton VPN protocol should I use for most stable connections?

Most users find WireGuard to be faster and often more stable on everyday networks. OpenVPN UDP can be more robust on some restrictive networks. If you’re having issues, try WireGuard first, then switch to OpenVPN UDP if needed.

Why does the kill switch cause apparent disconnects?

The kill switch is designed to block traffic if the VPN drops. If it triggers, you’ll see a connection loss. It’s useful for protection, but during troubleshooting you can temporarily disable it to test stability.

Can DNS leaks cause disconnects?

DNS leaks don’t cause disconnects per se, but they can expose your traffic if the VPN drops. Ensuring DNS is properly handled by the VPN or using trusted DNS resolvers helps prevent this.

How do I know if a server is overloaded?

If your connection slows significantly or drops frequently on a server you’ve been using, try another server in a different region.
