Info Endpoint Status - info.defi-oracle.io

Date: 2026-01-05
Status: ⚠️ PARTIAL - JSON Working, HTML 502 Error

---

Current Status

✅ Working Endpoints

Endpoint	Status	Response
/api/chain	✅ Working	Returns JSON chain data (480 bytes)
/chain.json	✅ Working	Returns JSON chain data (480 bytes)

⚠️ Issue

Endpoint	Status	Issue
/ (HTML)	❌ 502 Error	Cloudflare edge error (Nginx serves correctly locally)

---

Verification Results

✅ Local Access (via Nginx directly)

HTML Page:

curl http://127.0.0.1:80 -H 'Host: info.defi-oracle.io'

Result: ✅ Returns HTML (200 OK, 7157 bytes)

JSON Data:

curl http://127.0.0.1:80/chain.json -H 'Host: info.defi-oracle.io'

Result: ✅ Returns JSON (200 OK)

API Endpoint:

curl http://127.0.0.1:80/api/chain -H 'Host: info.defi-oracle.io'

Result: ✅ Returns JSON (200 OK)

⚠️ Public HTTPS Access

HTML Page:

curl https://info.defi-oracle.io

Result: ❌ 502 Bad Gateway (Cloudflare error)

JSON Data:

curl https://info.defi-oracle.io/chain.json

Result: ✅ Returns JSON (200 OK) - WORKING

Note: Both /api/chain and /chain.json work correctly via HTTPS

API Endpoint:

curl https://info.defi-oracle.io/api/chain

Result: ✅ Returns JSON (200 OK)

Root Cause Analysis

Nginx Configuration

• ✅ Server block configured correctly for info.defi-oracle.io
• ✅ Files accessible locally
• ✅ All endpoints respond correctly when accessed directly

Cloudflare Tunnel

• ⚠️ Tunnel routing configured to http://127.0.0.1:80
• ⚠️ JSON endpoints work (smaller response size)
• ❌ HTML endpoint fails (larger response - 7157 bytes)
• ⚠️ Possible timeout or buffering issue with larger responses

Observations

1. Small responses work: /api/chain and /chain.json both work (480 bytes)
2. Large response fails: / (HTML, 7157 bytes) returns 502
3. Local access works: Direct Nginx access returns 200 OK
4. Cloudflare error: 502 is coming from Cloudflare edge, not Nginx

---

Possible Causes

1. Cloudflare Tunnel Timeout: The tunnel may be timing out on larger responses
2. Cloudflare Buffer Limit: There may be a buffer size limit in the tunnel
3. Connection Issue: The tunnel connection may be dropping for longer responses
4. Tunnel Configuration: The tunnel may need specific timeout/buffer settings

---

Recommendations

Option 1: Check Cloudflare Tunnel Configuration

Verify tunnel settings in Cloudflare Dashboard:

• Check timeout settings
• Verify buffer size limits
• Review tunnel health status

Option 2: Optimize HTML Response

• Minify the HTML file to reduce size
• Enable gzip compression in Nginx
• Split content into smaller chunks if needed

Option 3: Use CDN Caching

• Enable Cloudflare caching for static content
• Set appropriate cache headers
• Use Cloudflare's HTML minification

Option 4: Direct File Serving

• Consider serving HTML from a CDN
• Use Cloudflare Pages or Workers
• Serve static files directly from Cloudflare

---

Current Workaround

For JSON Data (Working):

• Use /api/chain or /chain.json endpoints
• Both return complete chain information
• Suitable for API integrations

For HTML Page (Temporary):

• Access via direct IP (if exposed)
• Or wait for tunnel configuration fix

---

Next Steps

1. Investigate Cloudflare Tunnel Configuration

   • Check tunnel timeout settings
   • Review buffer size limits
   • Verify tunnel health

2. Optimize Nginx Configuration

   • Enable gzip compression
   • Add appropriate cache headers
   • Optimize response buffering

3. Test with Smaller HTML

   • Create a minimal test HTML page
   • Verify if size is the issue
   • Gradually increase size to find limit

---

Status:

• ✅ JSON endpoints fully operational (/api/chain and /chain.json)
• ⚠️ HTML endpoint (/) returns 502 from Cloudflare edge, but Nginx serves it correctly locally (200 OK)
• Root cause: Likely Cloudflare edge timeout or caching issue, not Nginx configuration

Recommendation: The JSON endpoints provide all necessary chain information. The HTML page issue may resolve after Cloudflare cache clears or tunnel configuration updates.
