Your VPN app may fail to connect, get stuck on "Connecting", show authentication errors, or disconnect frequently. This leaves your internet traffic unprotected and prevents access to geo-restricted content.
Internet connection down: VPN needs a working internet connection first.
VPN server overloaded: The server you're connecting to may be full.
Firewall blocking VPN: Your network may block VPN protocols.
Incorrect credentials: Wrong username or password.
VPN app outdated: Old app versions may have connection bugs.
ISP blocking VPN: Some ISPs or networks block VPN traffic.
• Disconnect from VPN and try loading a website.
• If internet doesn't work without VPN, fix your internet connection first.
• VPN needs a working internet connection to establish a tunnel.
• Open your VPN app and select a different server location.
• Choose a server geographically closer to you for better speeds.
• Some servers may be overloaded — switching usually helps.
• Go to your VPN app settings.
• Try switching protocols: WireGuard, OpenVPN (UDP), OpenVPN (TCP), IKEv2.
• WireGuard is usually fastest, OpenVPN TCP works best on restrictive networks.
• Close the VPN app completely.
• Restart your device.
• Restart your router.
• Open the VPN app and try connecting.
• Go to your app store and update the VPN app.
• New versions include protocol improvements and bug fixes.

• If it works, add the VPN app to your firewall's exception list.
If VPN still won't connect, contact your VPN provider's support team. Most providers have 24/7 live chat support.
Q: Why does my VPN keep disconnecting?
A: This is usually caused by unstable internet, server issues, or battery optimization killing the app. Disable battery optimization for your VPN app.

A: Yes, some ISPs and countries block VPN traffic. Use obfuscated servers (if your VPN offers them) or try the OpenVPN TCP protocol on port 443.
Q: Is it legal to use a VPN?
A: VPNs are legal in most countries. However, some countries restrict or ban VPN usage. Check your local laws.
Q: Does VPN slow down my internet?
A: Yes, VPN adds some overhead. Typically 10-30% speed reduction. Use WireGuard protocol and nearby servers to minimize speed loss.
