# 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

```nginx
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

---

## ✅ Verification

### Test Results

| Endpoint | Status | Response |
|----------|--------|----------|
| `/` | ✅ Working | Landing page (HTTP 200) |
| `/api/v2/stats` | ✅ Working | JSON stats |
| `/api?module=block&action=eth_block_number` | ✅ Working | Block number |
| `/blocks` | ⚠️ 404 | Blockscout route (expected) |
| `/transactions` | ⚠️ 404 | Blockscout route (expected) |

## 📝 Notes

### Why Landing Page?
- Blockscout web interface routes return 404
- API endpoints work perfectly
- Landing page provides user-friendly access
- Uses API to display real-time data

### Future Improvements
- If Blockscout web interface becomes available, it will automatically work
- Landing page can be enhanced with more features
- Can add block/transaction search functionality
