What to do
Windows: disconnect first
Does the Windows message mention the kill switch, or say protection is partial or cannot be confirmed? First click “Disconnect” in FuzeVPN: the block stops, whereas closing the window is not enough. If the internet stays blocked, follow the article on blocked internet access.
Windows: partial protection
Does the message say “Some protections remain active…”? The kill switch is off. With the VPN disconnected, turn “Kill switch” back on in “Settings → Privacy → Security”.
Connect again
Connect again. If FuzeVPN shows a wait time before retrying, connect again once it has passed. Otherwise, there is no need to wait, even with “Try again later”.
Extension: try again
Does the extension show “The server did not confirm creation of the new connection…”? Use the button to try again.
Subscription, device or email
Is FuzeVPN showing a different message? Subscription required, device limit reached, device no longer authorised or not recognised, email address to confirm: follow the matching article.

Location, permission or profile
Location full or unavailable, VPN permission denied on Android, OpenVPN profile revoked or expired: follow the matching article too.
A location is full or unavailableAndroid denies the VPN permission or another VPN is activeOpenVPN profile revoked or expired in the app: renew it
Internet without the VPN
Disconnect and check that the internet works without the VPN; if not, restore Wi-Fi or mobile data. On public Wi-Fi, first complete its sign-in or terms page. Then connect again.
Date and time
Check your device’s date and time.
Antivirus HTTPS scanning
Does the extension show “We could not verify the server’s security”? Turn off your antivirus’s HTTPS scanning, then connect again.
Another location
Choose another available location, then connect again.
Change protocol
Disconnect the VPN, then choose WireGuard or OpenVPN: on Windows, “Settings → Connection → VPN protocol”; on Android, “Connection → Advanced options → Protocol”. If your network blocks WireGuard, try OpenVPN. If the OpenVPN service is temporarily unavailable, choose WireGuard.
Another network
The internet works without the VPN, but FuzeVPN still won’t connect? Try another network: a different Wi-Fi network or mobile data.
Use the extension
If the apps cannot connect to any location from this network, use the FuzeVPN extension for your browser. It goes through port 443, like an ordinary HTTPS connection, and protects browsing in that browser.

Restart
Restart the app, then the device.
Windows: remove the device
On Windows, does the error come back on every network and every location? Remove this device from your account: this fixes the problem.
Windows: reinstall
Still getting the error? Reinstall the Windows app.

Write to support
If nothing works, or if the message comes back, write to support at contact@fuzevpn.com. Include your device or browser, the FuzeVPN version if shown, the protocol and your chosen location. Also mention the network used, when the problem occurred and the exact message.
Why it happens
- No usable internet access: Wi-Fi or mobile data is off. Public Wi-Fi may also be waiting for you to complete its sign-in page. The message can also appear when the internet works but the network does not let you reach FuzeVPN.
- On Windows, FuzeVPN could not find the WireGuard server’s address in time. The network was unavailable, or the address lookup (DNS) did not succeed. The cause may also lie with the PC itself. Depending on the message, the kill switch is still blocking the internet, is only partial or cannot be confirmed.
- The server is not responding, or OpenVPN cannot open its UDP connection (a type of network transmission) on the computer. The network may have been lost, it may filter UDP connections, or the location’s server may be unavailable. The Windows and Android apps use WireGuard and OpenVPN over UDP, without a fallback to port 443. On Windows, Automatic mode switches to OpenVPN if WireGuard does not start. If OpenVPN also fails, its message appears, even if you did not choose it.
- FuzeVPN’s online service that prepares OpenVPN connections is temporarily unavailable. The problem is on FuzeVPN’s side.
- FuzeVPN could not prepare the connection, and the message does not give the reason. On Windows, it asks you to try again later; on Android, an unexpected error interrupted the preparation.
- Extension: the server did not accept the browser’s connection session. Connecting again creates a new one.
- Extension: the server did not confirm creation of the requested connection, including the first connection. The extension then pauses automatic reconnection, so as not to create a duplicate connection.
- Extension: the browser could not verify the server’s security certificate. The cause: the computer’s clock is off, or an antivirus or firewall is scanning HTTPS connections. A network that intercepts the connection can also cause it.
Which protocol should I choose?
WireGuard and OpenVPN are the apps’ two protocols, in other words two ways of establishing the encrypted connection.
WireGuard, chosen by default, is the fastest. If your network blocks it, try OpenVPN.
On Windows, Automatic mode uses WireGuard. It switches to OpenVPN once, only if WireGuard does not start on the PC.
On Android, there is no Automatic mode: the app remembers your last choice.
The extensions use an HTTPS proxy, a relay encrypted with TLS 1.3, with no protocol setting.
