Reviewed 06 Nov 2026
Try these steps
- 1 Make sure your internet works without the VPN by opening a public website.
- 2 Disconnect the VPN, close the VPN app completely and open it again, then connect.
- 3 Check the date and time on your computer are correct — certificate errors often come from a wrong clock.
- 4 If you are on a hotel or public Wi-Fi, open a browser first and accept the network's sign-in page, then connect the VPN.
- 5 Restart the computer and try again.
- 6 Write down the exact error message or error number shown by the VPN app.
Before you start
Work through the steps in order and stop as soon as the problem is fixed. Never share passwords or verification codes with anyone.
When to contact support
If several people cannot connect, or the VPN shows a certificate or authentication error, open a ticket with the exact message.
