If HahaVPN cannot connect, try these checks in order:
- Confirm that the device can access the internet without the VPN.
- Disconnect HahaVPN, wait briefly, and connect again.
- Select another available VPN location.
- Confirm that the operating system has not removed or disabled HahaVPN’s VPN permission.
- Restart the app. If the problem continues, restart the device.
If the problem remains, email support@hahavpn.com and include the device platform, operating-system version, app version, and the error shown by the app. Do not send passwords, VPN browsing history, or other unnecessary sensitive information.
