DeFi Oracle Meta Mainnet Connectivity - Complete Diagnosis

Date: 2026-01-09
ChainID: 138 (0x8a)
Status: ⚠️ Internal Endpoints Working, Public Endpoints Down

---

Executive Summary

Internal RPC endpoints are fully operational, but public endpoints via Cloudflare tunnel are not accessible. This means:

• ✅ Internal network access: Working perfectly
• ❌ External/public access: Not working (Cloudflare tunnel issue)

---

✅ Working Endpoints (Internal Network)

All internal RPC endpoints are responding correctly:

1. RPC Translator: http://192.168.11.240:9545 ✅

   • ChainID: 0x8a (138)
   • Status: Fully operational

2. Core RPC: http://192.168.11.250:8545 ✅

   • ChainID: 0x8a (138)
   • Status: Fully operational

3. Permissioned RPC: http://192.168.11.251:8545 ✅

   • ChainID: 0x8a (138)
   • Status: Fully operational

4. Public RPC: http://192.168.11.252:8545 ✅

   • ChainID: 0x8a (138)
   • Status: Fully operational

❌ Non-Working Endpoints (Public/External)

Public endpoints via Cloudflare tunnel are returning error 1033:

1. rpc-http-pub.d-bis.org: ❌ Cloudflare error 1033
2. rpc-core.d-bis.org: ❌ Connection failed
3. rpc.d-bis.org: ❌ Connection failed

Root Cause: Cloudflare tunnel (VMID 102) is not running or misconfigured.

Issue Analysis

Cloudflare Tunnel Status

• VMID 102: Status unknown (needs verification)
• cloudflared binary: Not found in container
• cloudflared service: Not running or not configured

Expected Routing

Internet → Cloudflare → cloudflared (VMID 102) → Central Nginx (VMID 105) → RPC Node (VMID 2502)

Current Status: Tunnel is not operational, breaking the chain.

Solutions

Option 1: Use Internal Endpoints (Immediate Solution)

If you're on the internal network (192.168.11.0/24), use these endpoints:

For MetaMask/dApps:

• http://192.168.11.240:9545 (RPC Translator - ThirdWeb compatible)
• http://192.168.11.250:8545 (Core RPC)

For Development:

• http://192.168.11.251:8545 (Permissioned RPC)
• http://192.168.11.252:8545 (Public RPC)

Option 2: Fix Cloudflare Tunnel (For External Access)

To restore public endpoint access:

1. Install/Configure cloudflared on VMID 102
2. Configure tunnel in Cloudflare dashboard
3. Set up routing to central Nginx (VMID 105)
4. Verify tunnel is running

---

Recommended Action

For immediate use: Use internal endpoints if you're on the same network.

For public access: The Cloudflare tunnel needs to be configured and started. This requires:

• Cloudflare Zero Trust account access
• Tunnel configuration in Cloudflare dashboard
• cloudflared service running on VMID 102

Testing Commands

Test Internal Endpoints

# RPC Translator
curl -X POST http://192.168.11.240:9545 \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'

# Core RPC
curl -X POST http://192.168.11.250:8545 \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'

Test Public Endpoints

# Should work once tunnel is fixed
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}'

---

Next Steps

1. ✅ Internal endpoints verified working - Use these for now
2. ⏳ Fix Cloudflare tunnel - Install and configure cloudflared on VMID 102
3. ⏳ Configure tunnel routing - Set up hostname routing in Cloudflare dashboard
4. ⏳ Test public endpoints - Verify external access works
