An SSL/TLS certificate powers the padlock and HTTPS encryption. If it's expired, issued for the wrong domain or self-signed, the browser warns visitors and many leave. It's worth watching the expiry and renewing in time.
HTTPS encrypts the content, but your ISP still sees which domain you visit. GANVAS VPN hides that too by routing traffic through an encrypted tunnel.
The certificate must be issued for this exact domain (or via a *.domain wildcard). If not, the browser warns about an insecure connection.
Usually 2–4 weeks before expiry. Free certificates (Let's Encrypt) often auto-renew every 60–90 days.
