Frequently Asked Questions
Why is SSL certificate validation important?
SSL/TLS certificates ensure encrypted communication between servers and browsers, protecting sensitive data from interception. Regular validation prevents security warnings and expired certificates. Compare VPS performance with SSL support on our benchmarks page and find the best secure hosting on VPS providers.
How often should I check my SSL certificate?
Check SSL certificates at least monthly, especially 30-60 days before expiration. Use our Port Scanner to verify HTTPS (port 443) accessibility and DNS Lookup to ensure proper domain configuration. Track certificate renewals via Dashboard.
What does "Not Trusted" certificate status mean?
A "Not Trusted" status indicates the certificate is self-signed or issued by an untrusted Certificate Authority. Modern browsers will show security warnings. Get free trusted certificates from Let's Encrypt. Compare VPS hosting with built-in SSL support for easier management.
How do I fix SSL certificate errors?
Common fixes include renewing expired certificates, ensuring correct domain name matches, completing certificate chain, and verifying DNS records point to correct IP. Use our Htaccess to Nginx converter to properly configure SSL redirects. Check VPS hosting performance with SSL support on our benchmarks page.
