VPN Not Working? How to Fix It Step by Step (October 2026)

When a VPN isn’t working, the cause is nearly always one of a few things. The VPN server you picked may be busy or under maintenance, your network or ISP may be blocking the VPN protocol, a firewall or antivirus may be stopping the app, or the app itself may be out of date. Work through the fixes below in order (disconnect test, new server, new protocol, firewall exception, update or reinstall) and test after each one. Most people are back online within the first three steps.

As of October 22, 2026, “vpn not working” is trending, but we found no confirmed widespread outage behind it. Treat it as a local problem until your provider’s status page says otherwise.

First, figure out which kind of “not working” you have

Your fix depends on what you see. Each symptom below has a different likely cause.

Fix a VPN that won’t connect or has no internet

These steps follow the order ExpressVPN recommends, which matches what Proton VPN’s support pages suggest. Test after each step and stop as soon as it works.

1. Run the disconnect test

Disconnect the VPN and load a website.

• If the site loads, the problem is with the VPN connection. Carry on with the steps below.
• If it doesn’t load, your internet connection itself is down. Restart your router or switch networks first. The VPN can’t fix that.

2. Try a different server location

ExpressVPN lists a server location that is “under maintenance” or performing poorly as a top cause of failed connections. Pick another location, ideally a nearby one. Mullvad gave the same advice during a 2020 issue with its OpenVPN servers, so this step is worth trying first no matter which VPN you use.

3. Change the VPN protocol

Networks and ISPs sometimes interfere with specific VPN protocols. Proton’s guide puts it plainly: if you can’t connect using one protocol, try another.

1. Open your VPN app’s settings. In Proton VPN’s desktop apps, it’s Settings > Connection > Protocol.
2. If the app has an automatic option (Proton calls it Smart Protocol), make sure it’s on. Proton recommends leaving it enabled.
3. If automatic selection fails, choose a protocol by hand, for example WireGuard or OpenVPN.
4. If you’re on a school, work, hotel, or restricted network that actively blocks VPNs, try your provider’s obfuscated mode. Proton’s is called Stealth, and Proton says it’s particularly effective against active blocking.

Obfuscated protocols can be noticeably slower, so switch back once you’re on a normal network again. Protocol options also change over time. For example, Tom’s Guide reports that Proton removed OpenVPN from its Android app, leaving WireGuard and Stealth. If a menu option in this guide is missing, check your provider’s current help pages.

4. Check your firewall and antivirus

Security software is one of the most common blockers. Proton’s Windows troubleshooting page suggests this test:

1. Temporarily turn off your firewall and try connecting.
2. If the VPN now connects, turn the firewall back on right away.
3. Find the VPN app in your firewall’s settings and allow both incoming and outgoing connections for it.

ExpressVPN gives the same advice for third-party antivirus and “online security” apps: add the VPN as an exception instead of leaving protection off.

5. Turn off proxy settings

ExpressVPN lists proxy settings as a possible cause of “connected, no internet.” If you or your workplace set a system or browser proxy, disable it while you test the VPN.

6. Update, then reinstall

An outdated app is one of the causes ExpressVPN lists for connection failures. Update from the provider’s official website or your device’s official app store. If updating doesn’t fix it, uninstall and reinstall.

Also uninstall any other VPN apps you no longer use. Two VPN clients on the same device can conflict. If another VPN connects fine on the same device and network while yours doesn’t, that suggests the problem is specific to your provider’s app, server, or protocol rather than your network.

7. Check the clock and restart

A wrong system date and time can break secure connections, so make sure your device’s clock is set automatically. Then restart the device. It’s basic, but it clears stuck network adapters and background services.

Internet dead after turning the VPN off? Check the kill switch

A kill switch is a safety feature, not a bug. Proton’s kill switch documentation explains that it blocks all internet traffic if the VPN connection drops, so your real IP address and DNS requests don’t leak. Proton’s standard mode only kicks in on accidental drops. Its advanced mode on Windows and Linux allows internet access only while you’re connected to the VPN.

If you quit the app uncleanly, or a strict kill switch is on, you can end up with no internet at all. To fix it:

1. Reopen the VPN app and connect, or
2. Go to the app’s settings and turn the kill switch off (or switch to the standard mode), then check your connection.

On Linux in particular, some users on community forums have reported that a kill switch or DNS setting left behind by a VPN client kept blocking traffic after disconnecting. Those are individual reports, not official guidance, but they’re worth knowing about if the steps above don’t restore your connection.

Only one website or streaming app fails

If everything works except one service, the site is probably blocking your VPN’s IP address. That isn’t your VPN breaking. Streaming services commonly block IP addresses they identify as belonging to VPN or data-center providers, usually to enforce regional licensing. The usual result is an error message rather than an account ban. Your options:

• Try a different server in the same country.
• Clear the site’s cookies or try the website instead of the app (or the other way around).
• Disconnect the VPN for that service, or use your app’s split tunneling feature if it has one, so that service goes around the VPN.

Blocklists change constantly, so a server that worked last week can fail today. That’s normal, and no provider can promise it won’t happen.

Built-in Windows VPN connections (work or school VPNs)

If you set up a VPN in Windows Settings rather than using a provider’s app, the error message matters, so note its exact wording. On Microsoft Q&A, the common suggestions for L2TP/IPsec failures are:

1. Re-check the server address, sign-in method, and pre-shared key. A single typo is enough to cause a failure.
2. Delete the VPN connection and create it again.
3. Try a different VPN type, such as IKEv2 or SSTP, if your organization supports it.
4. Install pending Windows updates.

These come from community answers on Microsoft’s Q&A site, not an official Microsoft support article. For a work or school VPN, your IT helpdesk controls the server, so send them the exact error text before you change advanced system settings.

When to contact support

If you’ve tried a new server, a new protocol, a firewall exception, and a fresh install, contact your provider’s support through its official website or the app’s help menu. Tell them:

• Your device and operating system version
• The app version and the protocol you tried
• The exact error message
• What you’ve already tried

Many apps can send a diagnostic report from the help menu. ExpressVPN, for example, offers this. Use that instead of pasting logs into public forums, and never share your account password with anyone claiming to offer support.
