Benefits of Cloudflare Proxy
Security
-
DDoS Protection
- Absorbs attacks before they reach origin servers
- Unmetered DDoS mitigation
- Protects against Layer 3, 4, and 7 attacks
-
IP Address Hiding
- Origin server IPs hidden from public
- Prevents direct attacks on infrastructure
- Reduces server reconnaissance
-
SSL/TLS Management

- Automatic renewal
- Modern cipher suites
- TLS 1.3 support
-
Web Application Firewall (WAF)
- Blocks common exploits
- SQL injection protection
- XSS prevention
- Rate limiting
Performance
-
Global CDN
- Static assets cached worldwide
- Reduced latency for global users
- Faster page loads
-
Bandwidth Savings
- Cached content served from Cloudflare edge
- Reduces origin server bandwidth
- Lower hosting costs
-
Always Online
- Cached version served during origin downtime
- Improved reliability
-
Brotli Compression
- Automatic compression
- Faster page loads
- Reduced bandwidth
Decision Matrix: Proxy vs DNS-Only
When to Enable Proxy (Orange Cloud)
Use Cases:
- Public web interfaces (admin panels, portals, websites)
- HTTP/HTTPS traffic only
- Want DDoS protection
- Want global CDN caching
- Want to hide origin server IP
- Small to medium file sizes (<100MB)
Examples:
- Ghost CMS website
- Vaultwarden password manager
- Gitea code repository
- Wiki.js instances
- Paymenter billing portal
When to Use DNS-Only (Gray Cloud)
Use Cases:
- Email servers (SMTP, IMAP, POP3)
- Game servers (Minecraft, etc.)
- Large file downloads (>100MB)
- Infrastructure endpoints needing direct access
- Services with WebSocket-heavy requirements
- API endpoints with strict timeout requirements
Examples:
- mail.firefrostgaming.com
- panel.firefrostgaming.com (Wings direct connection)
- downloads.firefrostgaming.com
- All Minecraft game servers
SSL Certificate Requirements
Proxied Subdomains
Options:
-
Cloudflare Origin Certificate (Recommended)
- Generate in Cloudflare dashboard
- 15-year validity
- Supports wildcards (*.firefrostgaming.com)
- Free
- Only trusted by Cloudflare (perfect for proxied)
-
Let's Encrypt
- 90-day validity (auto-renewal required)
- Free
- Publicly trusted
- Works for both proxied and DNS-only
-
Commercial Certificate
- 1-year validity
- Publicly trusted
- Cost varies
DNS-Only Subdomains
Requirements:
- MUST use publicly trusted certificates
- Let's Encrypt recommended
- Cloudflare Origin Certificates won't work (not publicly trusted)
Current Status:
- mail.firefrostgaming.com: Let's Encrypt ✅
- panel.firefrostgaming.com: (check certificate status)
- vault.firefrostgaming.com: Let's Encrypt (expires May 14, 2026) ✅
Troubleshooting
"Dangerous Site" Warning
Symptoms: Chrome/Firefox shows SSL warning when accessing proxied subdomain
Cause: Origin server doesn't have valid SSL certificate for that subdomain
Solution:
- Generate Cloudflare Origin Certificate
- Install on origin server
- Update Nginx to use new certificate
- Reload Nginx
Example Fix (vault.firefrostgaming.com):
# On origin server
# Certificate already exists at: /etc/letsencrypt/live/vault.firefrostgaming.com/
# Enable Cloudflare proxy (orange cloud) in DNS settings
# Wait 5 minutes for DNS propagation
# Test: https://vault.firefrostgaming.com
521 Error (Web Server Down)
Symptoms: "Error 521: Web server is down"
Cause: Origin server not responding on proxied port
Checks:
- Service running on origin server
- Nginx/Apache listening on correct port
- Firewall allows Cloudflare IPs
- Origin server not blocking Cloudflare
Solution:
# Check service status
systemctl status nginx
# Check port listening
netstat -tlnp | grep :80
netstat -tlnp | grep :443
# Allow Cloudflare IPs (if using UFW)
# https://www.cloudflare.com/ips/
522 Error (Connection Timed Out)
Symptoms: "Error 522: Connection timed out"
Cause: Cloudflare can't connect to origin server
Checks:
- Origin server firewall blocking Cloudflare
- Origin server IP correct in DNS
- Origin server online
Solution:
- Verify A record points to correct IP
- Ensure firewall allows Cloudflare IP ranges
- Check origin server is responding
526 Error (Invalid SSL Certificate)
Symptoms: "Error 526: Invalid SSL certificate"
Cause: SSL/TLS mode is Full (strict) but origin certificate is invalid
Solution:
- Install valid SSL certificate on origin
- OR temporarily set SSL/TLS mode to "Full" (not recommended)
- OR use Cloudflare Origin Certificate
Monitoring
Check Proxy Status
Cloudflare Dashboard:
- Select domain (firefrostgaming.com)
- Go to DNS → Records
- Check cloud icon color:
- Orange = Proxied ✅
- Gray = DNS Only
Verify SSL
Test SSL configuration:
# Test from external location
curl -I https://vault.firefrostgaming.com
openssl s_client -connect vault.firefrostgaming.com:443 -servername vault.firefrostgaming.com
Analytics
Cloudflare Analytics Dashboard:
- Traffic volume per subdomain
- Bandwidth savings from caching
