## 🔴 Current Issues

### 1. Explorer Not Accessible ❌

**Symptom**: `https://explorer.d-bis.org` returns HTTP 404

**Possible Causes**:
1. Container VMID 5000 is not running
2. Blockscout service stopped
3. Nginx configuration issue
4. Cloudflare tunnel routing issue
5. DNS configuration issue

**Investigation Needed**:
```bash
# Check if container exists and is running (on Proxmox host)
ssh root@192.168.11.10
pct list | grep 5000
pct status 5000

# Check Blockscout service
pct exec 5000 -- systemctl status blockscout
pct exec 5000 -- docker ps

# Check Nginx
pct exec 5000 -- systemctl status nginx
pct exec 5000 -- nginx -t

# Check Cloudflare tunnel
pct exec 5000 -- systemctl status cloudflared
```

### 2. explorer-monorepo Backend API ❌

**Status**: Backend API server may not be running

**Documented Issues**:
- Backend API server not running on port 8080
- API endpoints returning HTTP 000 (connection refused)
- Database connection issues

**Location**: `/home/intlc/projects/proxmox/explorer-monorepo/backend/api/rest`

**Check Status**:
```bash
cd /home/intlc/projects/proxmox/explorer-monorepo
curl http://localhost:8080/health
ps aux | grep api-server
```

## 🔧 Troubleshooting Steps

### Step 1: Verify Container Status

```bash
# On Proxmox host
ssh root@192.168.11.10

# List all containers
pct list

# Check VMID 5000 specifically
pct status 5000
pct config 5000

# If container exists but is stopped
pct start 5000
```

### Step 2: Check Blockscout Service

```bash
# Enter container
pct exec 5000 -- bash

# Check Blockscout service
systemctl status blockscout
journalctl -u blockscout -n 50

# Check Docker containers
docker ps
docker-compose -f /opt/blockscout/docker-compose.yml ps

# Check Blockscout logs
docker-compose -f /opt/blockscout/docker-compose.yml logs --tail=50
```

### Step 3: Check Nginx Configuration

```bash
# Inside container
nginx -t
systemctl status nginx
tail -f /var/log/nginx/error.log

# Test local access
curl http://localhost:4000/api/v2/status
curl -k https://localhost/health
```

### Step 4: Check Cloudflare Tunnel

```bash
# Inside container
systemctl status cloudflared
journalctl -u cloudflared -n 50

# Check tunnel configuration
cat /etc/cloudflared/config.yml
```

### Step 5: Verify Database

```bash
# Inside container
sudo -u postgres psql -d blockscout -c "SELECT COUNT(*) FROM blocks;"
sudo -u postgres psql -d blockscout -c "SELECT MAX(number) FROM blocks;"
```

## 🚀 Recovery Actions

### Option 1: Restart Blockscout Service

```bash
# On Proxmox host
ssh root@192.168.11.10
pct exec 5000 -- systemctl restart blockscout
pct exec 5000 -- systemctl restart nginx
```

### Option 2: Redeploy Blockscout Container

If container is missing or corrupted:

```bash
# On Proxmox host
cd /home/intlc/projects/proxmox/smom-dbis-138-proxmox/scripts/deployment
export VMID_EXPLORER_START=5000
export PUBLIC_SUBNET=192.168.11
./deploy-explorer.sh

# Then run fix script
cd /home/intlc/projects/proxmox
./scripts/fix-blockscout-explorer.sh
```

### Option 3: Use explorer-monorepo

If Blockscout is not recoverable, the custom explorer can be deployed:

```bash
cd /home/intlc/projects/proxmox/explorer-monorepo
bash EXECUTE_DEPLOYMENT.sh
```

   - Check database connectivity

4. **Verify Cloudflare Configuration**
   - Confirm DNS record exists
   - Verify tunnel route is configured
   - Test tunnel connectivity

### If Container is Missing

1. **Deploy Container**
   ```bash
   ssh root@192.168.11.10
   cd /home/intlc/projects/proxmox/smom-dbis-138-proxmox/scripts/deployment
   export VMID_EXPLORER_START=5000
   ./deploy-explorer.sh
   ```

2. **Configure Services**
