First, check your mobile network connection to ensure your device is connected to the internet. Try accessing other websites or apps to confirm the network is working.
If the network is fine, switch to a different server node in the Click VPN app and try again.
Also, you can uninstall and then download the latest version from the Google Play or App Store.
If your current network restricts or blocks VPN traffic, switch to another Wi-Fi network or try using mobile data.
If the issue persists, all of our servers may be blocked by your country. We need some time to purchase new servers to handle this — please wait for a few hours and try reopening Click VPN again.
