## ⚠️ Remaining: Cloudflare DNS Configuration

### Current Status
- ❌ Cloudflare DNS record not configured (HTTP 522 error)
- ❌ Cloudflare tunnel route not configured
- ⚠️ **Manual configuration required** (API token not available)

### Required Actions

#### Step 1: Find Tunnel ID

**Option A: From Cloudflare Dashboard**
1. Go to: https://one.dash.cloudflare.com/
2. Navigate to: Zero Trust → Networks → Tunnels
3. Note the Tunnel ID (e.g., `abc123def456`)

**Option B: From Container (if accessible)**
```bash
ssh root@192.168.11.12  # pve2 node
pct exec 102 -- cloudflared tunnel list
# Or check config file:
pct exec 102 -- cat /etc/cloudflared/config.yml | grep -i tunnel
```

#### Step 2: Configure DNS Record

**In Cloudflare Dashboard**:
1. Go to: https://dash.cloudflare.com/
2. Select domain: `d-bis.org`
3. Navigate to: **DNS** → **Records**
4. Click **Add record**
5. Configure:
   ```
   Type: CNAME
   Name: explorer
   Target: <tunnel-id>.cfargotunnel.com
   Proxy status: 🟠 Proxied (orange cloud) - REQUIRED
   TTL: Auto
   ```
6. Click **Save**

#### Step 3: Configure Tunnel Route

**In Cloudflare Zero Trust Dashboard**:
1. Go to: https://one.dash.cloudflare.com/
2. Navigate to: **Zero Trust** → **Networks** → **Tunnels**
3. Select your tunnel
4. Click **Configure** → **Public Hostnames**
5. Click **Add a public hostname**
6. Configure:
   ```
   Subdomain: explorer
   Domain: d-bis.org
   Service: http://192.168.11.140:80
   Type: HTTP
   ```
7. Click **Save hostname**

#### Step 4: Verify

```bash
# Wait 1-5 minutes for DNS propagation
dig explorer.d-bis.org
curl https://explorer.d-bis.org/health

# Should return JSON response from Blockscout
```
