2. Duplicate DNS A Records ✅

Checked and verified no duplicate A records found for:

• ✅ besu.d-bis.org
• ✅ blockscout.d-bis.org
• ✅ explorer.d-bis.org
• ✅ d-bis.org

Note: Duplicates may have been cleaned up previously or didn't exist.

3. Cloudflare Tunnel Configuration Updated ✅

Tunnel: rpc-http-pub.d-bis.org (ID: 10ab22da-8ea3-4e2e-a896-27ece2211a05)

Updated via API to route:

• HTTP Endpoints → http://192.168.11.21:80 (Central Nginx)
• WebSocket Endpoints → Direct to RPC nodes (as configured)

HTTP Endpoints Configured:

• explorer.d-bis.org → http://192.168.11.21:80
• rpc-http-pub.d-bis.org → http://192.168.11.21:80
• rpc-http-prv.d-bis.org → http://192.168.11.21:80
• dbis-admin.d-bis.org → http://192.168.11.21:80
• dbis-api.d-bis.org → http://192.168.11.21:80
• dbis-api-2.d-bis.org → http://192.168.11.21:80
• mim4u.org → http://192.168.11.21:80
• www.mim4u.org → http://192.168.11.21:80

WebSocket Endpoints Configured (Direct Routing):

• rpc-ws-pub.d-bis.org → https://192.168.11.252:443
• rpc-ws-prv.d-bis.org → https://192.168.11.251:443

4. Network Connectivity Verified ✅

All network paths tested and working:

• ✅ pve2 (192.168.11.12) → ml110 (192.168.11.10)
• ✅ Central Nginx → RPC-1 (192.168.11.250)
• ✅ Central Nginx → RPC-2 (192.168.11.251)
• ✅ Central Nginx → RPC-3 (192.168.11.252)
• ✅ Central Nginx → DBIS Frontend (192.168.11.130)
• ✅ Central Nginx → Blockscout (192.168.11.140)
• ✅ Central Nginx → MIM (192.168.11.19)

🧪 Testing Results

Endpoint Tests

After fixes applied, test endpoints:

# RPC Public HTTP
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}'

# Explorer
curl https://explorer.d-bis.org/api/v2/stats

# DBIS Admin
curl https://dbis-admin.d-bis.org

# MIM
curl https://mim4u.org

# MIM WWW Redirect
curl -I https://www.mim4u.org  # Should redirect to mim4u.org

📝 Scripts Created

1. scripts/fix-all-infrastructure-issues.sh

   • Comprehensive fix script
   • Creates DNS records
   • Removes duplicates
   • Verifies connectivity

2. scripts/update-cloudflare-tunnel-config.sh

   • Updates tunnel configuration via API
   • Routes HTTP endpoints to central Nginx
   • Preserves WebSocket direct routing

---

⏱️ Timeline

• DNS Propagation: 1-5 minutes
• Tunnel Configuration: Applied immediately (takes 1-2 minutes to reload)
• Full System Ready: ~5 minutes after script execution

---

✅ Verification Checklist

• DNS CNAME records created
• Duplicate A records checked
• Tunnel configuration updated
• Network connectivity verified
• Endpoint testing (wait for DNS propagation)
• Tunnel status shows HEALTHY (check in 1-2 minutes)

---

🎯 Next Steps

1. Wait 1-2 minutes for DNS propagation and tunnel reload
2. Check tunnel status in Cloudflare dashboard (should show HEALTHY)
3. Test all endpoints using the test commands above
4. Monitor logs for any routing issues
