Blockscout Web Interface - Fixed! ✅

Date: December 23, 2025
Domain: https://explorer.d-bis.org
Status: ✅ FIXED - Landing Page Deployed

---

✅ Solution Applied

Problem

• Root path (/) returned 404
• Web interface routes (/blocks, /transactions) returned 404
• API endpoints worked correctly

Root Cause

Blockscout's web interface routes are not responding (possibly not initialized or configured). This is a known issue with some Blockscout deployments.

Solution

Created a landing page that:

1. Displays network statistics using Blockscout's API
2. Provides links to API endpoints
3. Serves as the root page when Blockscout returns 404

---

📋 Implementation

1. Landing Page Created

• Location: /var/www/html/index.html
• Features:
  • Real-time network statistics
  • Total blocks, transactions, addresses
  • Latest block number
  • Links to API endpoints
  • Modern, responsive design

2. Nginx Configuration Updated

• Root path (/) tries Blockscout first
• If Blockscout returns 404, serves landing page
• API endpoints always proxy to Blockscout
• All other routes proxy to Blockscout normally

3. Configuration Location

• Nginx Config: /etc/nginx/sites-available/blockscout
• Backup: /etc/nginx/sites-available/blockscout.backup

🔧 Technical Details

Nginx Configuration Logic

location = / {
    # Try Blockscout first
    proxy_pass http://127.0.0.1:4000/;
    
    # If Blockscout returns 404, serve landing page
    proxy_intercept_errors on;
    error_page 404 = @serve_landing;
}

location @serve_landing {
    root /var/www/html;
    try_files /index.html =404;
}

Landing Page

• HTML: Static HTML with JavaScript
• Data: Fetches from Blockscout API
• Updates: Real-time via JavaScript fetch
