⚠️ 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

[⚠️] 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

How to Complete Implementation

Quick Path (Automated)

1. Fix Blockscout (manual - see implementation guide):

   # 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:

   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:

   curl -I https://explorer.d-bis.org/api/v2/stats
   # Should return HTTP 200
