TLS Certificate Guide

Set up and manage TLS certificates to secure your web applications. Covers certificate types, automated renewal with Let's Encrypt, certificate chain configuration, and troubleshooting common TLS issues.

Usage

Ask about obtaining TLS certificates, configuring HTTPS, or troubleshooting certificate errors.

Examples

• "How do I set up Let's Encrypt with automatic renewal?"
• "What is the difference between DV, OV, and EV certificates?"
• "My site shows a certificate chain error — how do I fix it?"

Guidelines

• Use Let's Encrypt for free, automated DV certificates
• Always include the full certificate chain in your server configuration
• Set up automated renewal with at least 30 days before expiry
• Use HSTS headers to enforce HTTPS after confirming it works correctly
• Monitor certificate expiry dates and alert well before they expire
