**Date**: 2026-01-03  
**Status**: ✅ **ALL FIXES APPLIED**

---

## Summary

Applied comprehensive fixes to all RPC nodes to resolve configuration issues and enable proper RPC access.

---

## Fixes Applied

### 1. Host Allowlist Restrictions (VMID 2400, 2501, 2502)
- **Issue**: RPC endpoints returning "Host not authorized"
- **Root Cause**: Besu requires explicit `rpc-http-host-allowlist` configuration for external access
- **Fix**: Added `rpc-http-host-allowlist=["*"]` to config files
- **Config Files Updated**:
  - VMID 2400: `/etc/besu/config-rpc-thirdweb.toml`
  - VMID 2501: `/etc/besu/config-rpc-public.toml`
  - VMID 2502: `/etc/besu/config-rpc-public.toml`

### 2. Missing Genesis Files (VMID 2401, 2402, 2503-2508)
- **Issue**: Services failing due to missing `/genesis/genesis.json`
- **Fix**: Copied `genesis.json` and `static-nodes.json` from working node (VMID 2500)
- **Files Copied**: 
  - `/genesis/genesis.json`
  - `/genesis/static-nodes.json`

### 3. Fast Sync Configuration Error (VMID 2401, 2402)
- **Issue**: `--fast-sync-min-peers can't be used with FULL sync-mode`
- **Fix**: Removed `fast-sync-min-peers` option from config files
- **Config File**: `/etc/besu/config-rpc-thirdweb.toml`

### 4. Permissions File Path (VMID 2503-2508)
- **Issue**: Services looking for `/etc/besu/permissions-nodes.toml` but file was in `/permissions/permissions-nodes.toml`
- **Fix**: Copied permissions file to `/etc/besu/permissions-nodes.toml` on all affected nodes

## Configuration Changes

### Host Allowlist
Added to all affected config files:
```toml
rpc-http-host-allowlist=["*"]
```

This allows external connections to the RPC endpoints.
