# All Fixes Complete - Summary

**Date**: 2025-01-27  
**Status**: ✅ **NGINX & BESU FIXED** | ⚠️ **CLOUDFLARED ROUTING NEEDS UPDATE**

---

## ✅ Completed Fixes

### 1. Nginx Configuration on VMID 2502 ✅

**Status**: ✅ **FULLY WORKING**

- Added public endpoint server blocks for `rpc-http-pub.d-bis.org` and `rpc-ws-pub.d-bis.org`
- Configured **WITHOUT** JWT authentication
- Fixed Host header to send `localhost` to Besu (required for Besu host validation)
- Using existing SSL certificates
- **Local test**: ✅ Working (`{"jsonrpc":"2.0","id":1,"result":"0x8a"}`)

**Configuration**: `/etc/nginx/sites-available/rpc` on VMID 2502

### 2. Besu Configuration on VMID 2502 ✅

**Status**: ✅ **RUNNING SUCCESSFULLY**

Fixed all configuration issues:
- ✅ Genesis file path: `/etc/besu/genesis.json`
- ✅ Static nodes path: `/etc/besu/static-nodes.json`
- ✅ Permissions file path: `/etc/besu/permissions-nodes.toml`
- ✅ Removed incompatible sync mode options
- ✅ Removed legacy transaction pool options
- ✅ Besu is running and responding correctly

**Direct Besu Test**: ✅ Working (`{"jsonrpc":"2.0","id":1,"result":"0x8a"}`)

### 3. Cloudflared Tunnel Routing ⚠️

**Status**: ⚠️ **NEEDS UPDATE**

**Issue**: Cloudflared tunnel is still routing to the wrong VMID.

**Current Routing** (based on external test failure):
- Cloudflared → Probably still routing to VMID 2501 (192.168.11.251) or 2500 (192.168.11.250)

**Required Routing**:
- Cloudflared → VMID 2502 (192.168.11.252:443)

**Script Updated**: ✅ The setup script has been updated to route to VMID 2502

## 🔧 Action Required: Update Cloudflared Tunnel

Since Cloudflared appears to be managed via Cloudflare Dashboard (VMID 102 not found locally), you need to update it there:

### Option 1: Cloudflare Dashboard (Recommended)

1. **Log in** to Cloudflare Dashboard
2. **Go to**: Zero Trust → Networks → Tunnels
3. **Select** your tunnel (or the tunnel handling `rpc-http-pub.d-bis.org`)
4. **Find** the hostname entries:
   - `rpc-http-pub.d-bis.org`
   - `rpc-ws-pub.d-bis.org`
5. **Change service** from:
   - Current: `https://192.168.11.251:443` (or `https://192.168.11.250:443`)
   - To: `https://192.168.11.252:443`
6. **Save** changes
7. **Wait** 2-3 minutes for changes to propagate

### Option 2: If Managed Locally

If cloudflared is running on a different VMID or server:

1. Find where cloudflared config is located
2. Update `/etc/cloudflared/config.yml`:
   ```yaml
   ingress:
     - hostname: rpc-http-pub.d-bis.org
       service: https://192.168.11.252:443
     - hostname: rpc-ws-pub.d-bis.org
       service: https://192.168.11.252:443
   ```
3. Restart cloudflared: `systemctl restart cloudflared`

## ✅ Verification

### Local Test (Working ✅)

```bash
# Direct Besu
ssh root@192.168.11.10 "pct exec 2502 -- curl -s -X POST http://127.0.0.1:8545 -H 'Content-Type: application/json' -d '{\"jsonrpc\":\"2.0\",\"method\":\"eth_chainId\",\"params\":[],\"id\":1}'"
# Returns: {"jsonrpc":"2.0","id":1,"result":"0x8a"}

# Through Nginx locally
ssh root@192.168.11.10 "pct exec 2502 -- curl -k -s -X POST https://localhost -H 'Host: rpc-http-pub.d-bis.org' -H 'Content-Type: application/json' -d '{\"jsonrpc\":\"2.0\",\"method\":\"eth_chainId\",\"params\":[],\"id\":1}'"
# Returns: {"jsonrpc":"2.0","id":1,"result":"0x8a"}
```

### External Test (Will work after Cloudflared update)

```bash
curl -X POST https://rpc-http-pub.d-bis.org \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'
# Expected: {"jsonrpc":"2.0","id":1,"result":"0x8a"}
```

## 📋 Final Architecture

```
Internet
  ↓
Cloudflare DNS/SSL (rpc-http-pub.d-bis.org)
  ↓
Cloudflared Tunnel
  ↓ (NEEDS UPDATE to route here)
192.168.11.252:443 (VMID 2502)
  ↓
Nginx (listening on port 443)
  ↓ (sends Host: localhost)
Besu RPC (127.0.0.1:8545)
  ↓
Response: {"jsonrpc":"2.0","id":1,"result":"0x8a"}
```

---

## 🎯 Summary

✅ **Nginx**: Fully configured and working  
✅ **Besu**: All configuration issues fixed, running successfully  
⚠️ **Cloudflared**: Routing needs to be updated to VMID 2502

**Next Step**: Update Cloudflared tunnel routing in Cloudflare Dashboard (or local config) to point to `https://192.168.11.252:443`

Once Cloudflared routing is updated, MetaMask should be able to connect successfully! 🎉
