2. Enable HSTS for your domain
3. Set the max-age (recommended: 31536000 seconds)
4. Include subdomains if needed

Troubleshooting Common SSL Issues

Mixed Content Warnings

Problem: Page loads with SSL but shows warnings Solution:

• Update all HTTP links to HTTPS
• Check images, scripts, and stylesheets
• Use protocol-relative URLs (//example.com)

Certificate Chain Issues

Problem: SSL certificate not trusted by browsers Solution:

• Install intermediate certificates
• Verify certificate chain completeness
• Contact your SSL provider for bundle files

Certificate Mismatch

Problem: Certificate doesn't match domain name Solution:

• Ensure certificate includes all domain variations
• Consider wildcard certificates for subdomains
• Regenerate certificate with correct domain names

SSL Certificate Management

Monitoring Certificate Expiration

1. Check expiration dates regularly in cPanel
2. Set up renewal reminders 30 days before expiration
3. Enable auto-renewal for Let's Encrypt certificates

Renewing SSL Certificates

For Let's Encrypt:

• Certificates auto-renew every 90 days
• Manual renewal available in cPanel

For Purchased Certificates:

• Purchase renewal from your SSL provider
• Follow installation process with new certificate
• Update any hardcoded certificate references

Certificate Backup

1. Export certificate files from cPanel
2. Store securely with private keys
3. Document certificate details for reference

Security Best Practices

SSL Configuration

• Use strong encryption (TLS 1.2 or higher)
• Disable weak ciphers and protocols
• Enable Perfect Forward Secrecy
• Implement OCSP stapling

Regular Maintenance

• Monitor certificate health using SSL testing tools
• Update certificates before expiration
• Review security logs for anomalies
• Keep cPanel updated for latest security features

Testing Your SSL Installation

Online SSL Testing Tools

1. SSL Labs SSL Test (ssllabs.com/ssltest/)

   • Comprehensive security analysis
   • Grade-based scoring system
   • Detailed vulnerability reports

2. SSL Checker Tools

   • Verify certificate installation
   • Check certificate chain
   • Validate expiration dates

Browser Testing

1. Visit your website using HTTPS
2. Check for lock icon in address bar
3. Verify certificate details by clicking the lock
4. Test on multiple browsers and devices

Advanced SSL Features

Wildcard Certificates

Secure unlimited subdomains with a single certificate:
