|
|
|
|
**Date**: 2026-01-09
|
|
**ChainID**: 138
|
|
**Issue**: Unable to connect to DeFi Oracle Meta Mainnet
|
|
|
|
---
|
|
|
|
## Problem Summary
|
|
|
|
The DeFi Oracle Meta Mainnet (ChainID 138) is not accessible. RPC endpoints are not responding.
|
|
|
|

|
|
|
|
## RPC Endpoints Tested
|
|
|
|
### Primary RPC Nodes
|
|
- **192.168.11.250:8545** (VMID 2500) - ❌ Not responding
|
|
- **192.168.11.251:8545** (VMID 2501) - ❌ Not responding
|
|
- **192.168.11.252:8545** (VMID 2502) - ❌ Not responding
|
|
|
|
### RPC Translator
|
|
- **192.168.11.240:9545** (VMID 2400) - ⏳ Testing...
|
|
|

|
|
|
|
## Expected RPC Endpoints
|
|
|
|
Based on configuration files, the following RPC endpoints should be available:
|
|
|
|
1. **Internal Network**:
|
|
- `http://192.168.11.250:8545` (Core RPC)
|
|
- `http://192.168.11.251:8545` (Permissioned RPC)
|
|
- `http://192.168.11.252:8545` (Public RPC)
|
|
|
|
2. **Public Endpoints** (via Cloudflare Tunnel):
|
|
- `https://rpc-core.d-bis.org`
|
|
- `https://rpc-http-pub.d-bis.org`
|
|
- `https://rpc-http-prv.d-bis.org`
|
|
- `https://rpc.public-0138.defi-oracle.io`
|
|
|
|
3. **RPC Translator**:
|
|
- `http://192.168.11.240:9545` (ThirdWeb compatible)
|

|
## Diagnostic Steps
|
|
|
|
### 1. Check RPC Node Status
|
|
```bash
|
|
# Check container status
|
|
ssh root@192.168.11.10 "pvesh get /nodes/\$(hostname)/lxc/2500/status/current"
|
|
|
|
# Check Besu service
|
|
ssh root@192.168.11.10 "pct exec 2500 -- systemctl status besu-rpc"
|
|
|
|
# Check if RPC port is listening
|
|
ssh root@192.168.11.10 "pct exec 2500 -- netstat -tuln | grep 8545"
|
|
```
|
|
|
|
### 2. Test Local RPC Connection
|
|
```bash
|
|
# Test from within the container
|
|
ssh root@192.168.11.10 "pct exec 2500 -- curl -X POST http://127.0.0.1:8545 \
|
|
-H 'Content-Type: application/json' \
|
|
-d '{\"jsonrpc\":\"2.0\",\"method\":\"eth_chainId\",\"params\":[],\"id\":1}'"
|
|
```
|
|
|
|
### 3. Check Network Connectivity
|
|
```bash
|
|
# Test network connectivity
|
|
ping 192.168.11.250
|
|
nc -zv 192.168.11.250 8545
|
|
```
|
|
|
|
### 4. Check Firewall Rules
|
|
```bash
|
|
# Check if firewall is blocking connections
|
|
iptables -L -n | grep 8545
|
|
```
|
|
|

|
|
|
|
## Possible Causes
|
|
|
|
1. **RPC Nodes Not Running**
|
|
- Containers may be stopped
|
|
- Besu services may have crashed
|
|
- Services may not be started
|
|
|
|
2. **Network Issues**
|
|
- Firewall blocking connections
|
|
- Network routing problems
|
|
- Interface configuration issues
|
|
|
|
3. **Service Configuration Issues**
|
|
- RPC API not enabled
|
|
- Wrong port configuration
|
|
- Service binding to wrong interface
|
|
|
|
4. **Resource Issues**
|
|
- Out of memory
|
|
- Disk space full
|
|
- CPU overload
|

|
## Next Steps
|
|
|
|
1. ✅ Check RPC node container status
|
|
2. ✅ Check Besu service status
|
|
3. ✅ Verify RPC port is listening
|
|
4. ⏳ Check service logs for errors
|
|
5. ⏳ Verify network connectivity
|
|
6. ⏳ Check firewall rules
|
|
7. ⏳ Restart services if needed
