Preventing common DNS and SSL-related issues.

What's New in v0.9.1

New Features

• Ubuntu Version Check: Added support for both Ubuntu 22.04 and 24.04 LTS with automatic version validation
• DNS A Record Verification: Automatic DNS verification before domain setup to prevent SSL certificate issues
• Server IP Display: Shows current server IP address during domain configuration
• DNS Match Validation: Verifies that domain A record points to the correct server IP
• CloudFlare SSL Proxy Warning: Automatic warning and instructions for CloudFlare users to disable SSL proxy mode

Improvements

• Better pre-installation validation to catch configuration issues early
• Clearer error messages for DNS mismatches with detailed troubleshooting info
• CloudFlare users are guided to set DNS to "DNS Only" mode before SSL installation
• Option to override validation checks for advanced users
• Enhanced installation flow with step-by-step DNS configuration guidance

Important Notes

For CloudFlare Users:
If you're using CloudFlare, you must disable the SSL/TLS Proxy (orange cloud) and set it to "DNS Only" (gray cloud) mode. The installer will provide step-by-step instructions during SSL setup. This is required because we provide SSL certificates via Let's Encrypt directly on the server.

Technical Details

The installer now:

• Checks Ubuntu version compatibility before proceeding
• Uses dig to query DNS records via Google DNS (8.8.8.8)
• Compares resolved IP with server IP to detect misconfigurations
• Provides interactive prompts with color-coded warnings and success messages
• Warns CloudFlare users about SSL proxy conflicts
