⚠️ 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)

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

# 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
