Port 4000 Implementation - COMPLETE ✅

Last Updated: 2026-01-31
Document Version: 1.0
Status: Active Documentation

Date: 2026-01-18
Status: ✅ IMPLEMENTATION COMPLETE

Implementation Summary

The port 4000 direct route for explorer.d-bis.org has been successfully implemented and verified.

✅ Verification Results

Port 4000 Direct Access

curl -I http://192.168.11.140:4000/api/v2/stats

Result: ✅ HTTP 200

Public Domain Access

curl -I https://explorer.d-bis.org/api/v2/stats

Result: ✅ HTTP 200

API Response

The Blockscout API is responding correctly with valid JSON data including:

Total blocks: 1,048,760
Total transactions: 13,156
Network statistics

Implementation Steps Completed

✅ Step 1: Check Blockscout service status and configuration
✅ Step 2: Fix Blockscout to listen on 0.0.0.0:4000
✅ Step 3: Verify Blockscout is accessible on port 4000
✅ Step 4: Update NPMplus configuration
✅ Step 5: Verify public domain works

Current Configuration

Architecture

Internet → NPMplus → 192.168.11.140:4000 (Blockscout directly)

Old Route: NPMplus → 192.168.11.140:80 (nginx) → 127.0.0.1:4000 (Blockscout)
New Route: NPMplus → 192.168.11.140:4000 (Blockscout directly) ✅

Benefits Achieved

✅ Removed nginx proxy layer (one less hop)
✅ Reduced latency
✅ Fewer points of failure
✅ Simpler architecture
✅ Fixed 502 Bad Gateway errors

Test Commands

Verify Direct Access

curl -I http://192.168.11.140:4000/api/v2/stats

Verify Public Domain

curl -I https://explorer.d-bis.org/api/v2/stats

Check API Response

curl -s https://explorer.d-bis.org/api/v2/stats | jq .

Conclusion

The direct route implementation is complete and operational. The explorer is now accessible via both:

Direct Network Access: http://192.168.11.140:4000
Public Domain: https://explorer.d-bis.org

Both routes are working correctly and returning HTTP 200 responses.
