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:

   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 ✅)

# 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)

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! 🎉
