Common causes include:
Choose another server in the same country or a nearby location. If one server is overloaded or blocked, a different endpoint often connects immediately.
Change between WireGuard, OpenVPN, IKEv2, or the app's automatic setting. Some networks block certain protocols, so testing another one is one of the fastest fixes.
Temporarily turn off firewall or antivirus features that inspect network traffic, then test the VPN again. If it works, add the VPN app to the allow list instead of leaving security off.
Make sure you are signed into the correct account and that your subscription is active. Some VPN apps will silently fail to connect if billing has expired or the account is locked.
Close the VPN app, restart your device, and reconnect your network. On desktop, disabling and re-enabling the Wi-Fi or Ethernet adapter can clear stale tunnel state.
Install the latest version of the VPN client. If the problem persists, uninstall the app, reboot, and reinstall it from the official source to remove corrupted settings or drivers.
Try your VPN on a different Wi-Fi network or mobile hotspot. If it works elsewhere, your original network is probably blocking VPN traffic or using strict filtering rules.
A VPN stuck on Connecting usually means the server is unreachable, your firewall is blocking traffic, or the protocol is being filtered by your network. Try another server, change the protocol, or test with the firewall off.
Frequent disconnections are usually caused by unstable internet, power-saving settings, or an overloaded server. Keep your connection stable, disable sleep while connected, and try a less busy server.
Windows VPN issues can come from outdated drivers, conflicting security software, or blocked ports. Update the VPN app, refresh the network driver, and test with third-party firewall tools disabled.
Some carriers block or throttle VPN traffic, especially on certain protocols. Try switching to WireGuard or OpenVPN UDP, and test on Wi-Fi to compare behavior.
Yes. Some routers, public Wi-Fi networks, and enterprise networks filter VPN ports or inspect encrypted traffic. If the VPN works on a hotspot but not on your main network, the router or network rules are likely the problem.
Try the same service on a different device or network. If it works elsewhere, the issue is local to your device or network. If it fails everywhere, the service itself may be down - check Downdetector or the service's official status page to confirm.
Yes. A full restart (not just closing the app) clears stale connections, frees memory, and resolves the majority of intermittent glitches. Try this before deeper troubleshooting steps.
Open the App Store (iPhone) or Google Play Store (Android) and search for the app - if an Update button appears, tap it. On desktop apps, look for an About or Check for Updates option in the menu. Outdated apps often break after server-side updates.
If clearing the cache, updating, and restarting have all failed, reinstall the app as a last resort. A clean reinstall removes corrupted data, settings, and permissions that the standard fix steps cannot reach. Your account and saved data are stored in the cloud, so you won't lose anything by reinstalling.
