# VMID 2400 Routing Configuration - Summary

## ✅ Completed

1. **Tunnel Configuration Updated**
   - Tunnel ID: `26138c21-db00-4a02-95db-ec75c07bda5b`
   - Routes `rpc.public-0138.defi-oracle.io` → `http://127.0.0.1:80` (Nginx)
   - Status: Healthy

2. **Nginx Configuration**
   - Routes HTTP requests → `127.0.0.1:8545` (Besu HTTP RPC)
   - Routes WebSocket requests → `127.0.0.1:8546` (Besu WebSocket RPC)
   - WebSocket detection via `$http_upgrade` header
   - Service: Running

3. **Cloudflare SSL/TLS**
   - Mode: `full` (correct)
   - Domain: `defi-oracle.io`

4. **Service Verification**
   - Besu RPC: Working (Chain ID: 0x8a / 138)
   - Cloudflared: Running
   - Nginx: Running

## ⚠️ Remaining Issue

**SSL Handshake Failure** on public endpoint:
- `https://rpc.public-0138.defi-oracle.io` fails with SSL handshake error
- Internal routing works correctly
- Likely Cloudflare edge configuration issue

## Next Steps (Manual)

1. **Verify DNS Proxy Status**
   - Cloudflare Dashboard → DNS
   - Ensure `rpc.public-0138.defi-oracle.io` CNAME is proxied (🟠 orange cloud)

2. **Check SSL/TLS Settings**
   - Cloudflare Dashboard → SSL/TLS → Overview
   - Verify mode is "Full" (currently set correctly)

3. **Clear Cloudflare Cache** (if needed)
   - Cloudflare Dashboard → Caching → Purge Everything

4. **Wait for Propagation**
   - DNS/SSL changes may take 5-15 minutes

## Architecture

```
https://rpc.public-0138.defi-oracle.io
    ↓ Cloudflare Tunnel
http://127.0.0.1:80 (Nginx)
    ↓ Nginx Routing
    ├─ HTTP → 127.0.0.1:8545
    └─ WebSocket → 127.0.0.1:8546
```

**Status**: Configuration complete, awaiting Cloudflare edge resolution
