## ⚠️ Pending Items (Require Manual Action)

### 1. Blockscout Configuration ⚠️ **BLOCKER**

**Status**: Blockscout service is not running or not configured for port 4000

**Required Actions**:
1. Access Proxmox host (192.168.11.11)
2. Determine Blockscout configuration method (Docker or systemd)
3. Configure Blockscout to listen on `0.0.0.0:4000` (not `127.0.0.1:4000`)
4. Restart Blockscout service
5. Verify: `curl -I http://192.168.11.140:4000/api/v2/stats` returns HTTP 200

**See**: `docs/04-configuration/PORT_4000_IMPLEMENTATION_GUIDE.md` for detailed steps

### 2. NPMplus Configuration Update ⚠️ **WAITING**

**Status**: Cannot proceed until Blockscout is accessible on port 4000

**Will be completed automatically** once Blockscout is fixed:
- Script ready: `scripts/complete-port-4000-implementation.sh`
- Or manual: Update `explorer.d-bis.org` Forward Port: 80 → 4000

### 3. Public Domain Verification ⚠️ **WAITING**

**Status**: Cannot verify until NPMplus is updated

**Will be tested** after NPMplus update:
- Test: `curl -I https://explorer.d-bis.org/api/v2/stats`
- Expected: HTTP 200 (not 502)

---

## Current System State

### Blockscout (VMID 5000)
- ❌ **Service Status**: Inactive or not running
- ❌ **Port 4000**: Not listening
- ❌ **Network Access**: Not accessible from network
- ✅ **Configuration Files**: Updated to reference port 4000 (planning)

### NPMplus
- ✅ **Configuration Scripts**: Updated to use port 4000
- ⏸️ **Running Configuration**: Still using port 80 (cannot update until Blockscout fixed)
- ✅ **Update Scripts**: Ready to run once Blockscout is accessible

### Network Connectivity
- ✅ **Proxmox Host**: Accessible (SSH working)
- ❌ **Port 4000**: Not accessible (`curl` fails)
- ⏸️ **Public Domain**: Not tested (waiting for NPMplus update)

## Implementation Workflow

```
[✅] 1. Investigation & Documentation
     └─> COMPLETE

[✅] 2. Script Creation & Automation
     └─> COMPLETE

[⚠️] 3. Blockscout Configuration ← CURRENT BLOCKER
     └─> REQUIRES MANUAL ACTION
         • Configure Blockscout to listen on 0.0.0.0:4000
         • Restart service
         • Verify accessibility

[⏸️] 4. NPMplus Update
     └─> WAITING FOR STEP 3
         • Will run automatically via script
         • Or can be done manually via UI

[⏸️] 5. Public Domain Verification
     └─> WAITING FOR STEP 4
         • Test: curl -I https://explorer.d-bis.org/api/v2/stats
```

## How to Complete Implementation

### Quick Path (Automated)

1. **Fix Blockscout** (manual - see implementation guide):
   ```bash
   # From Proxmox host
   cd /home/intlc/projects/proxmox
   ./scripts/complete-port-4000-implementation.sh
   ```

2. **If Blockscout is fixed**, the script will:
   - Automatically verify port 4000 accessibility
   - Update NPMplus configuration
   - Test public domain

### Manual Path

1. **Fix Blockscout** (see implementation guide for details):
   - Check service/container status
   - Update configuration (Docker or systemd)
   - Restart Blockscout

2. **Verify Blockscout**:
   ```bash
   curl -I http://192.168.11.140:4000/api/v2/stats
   # Should return HTTP 200
   ```

3. **Update NPMplus**:
   - Via script: `./scripts/apply-direct-blockscout-route.sh`
   - Or manually: Update `explorer.d-bis.org` Forward Port: 80 → 4000

4. **Verify Public Domain**:
   ```bash
   curl -I https://explorer.d-bis.org/api/v2/stats
   # Should return HTTP 200
   ```
