📋 Configuration Details

NPMplus Access

• Dashboard: https://192.168.11.166:81
• User: nsatoshi2007@hotmail.com
• Container: npmplus (VMID 10233 on 192.168.11.11)

Backend Server

• VM: 192.168.11.211 (VMID 2101 on 192.168.11.10)
• Nginx: ✅ Running
• Local Status: ✅ HTTP 200 OK

---

⚠️ Network Connectivity Note

Current Status:

• Proxy host is configured correctly in NPMplus
• Backend server is running and accessible locally
• Network connectivity between NPMplus container and backend VM needs verification

If experiencing 502 errors:

1. Verify network routing between 192.168.11.11 (NPMplus host) and 192.168.11.211 (backend)
2. Check firewall rules on both VMs
3. Ensure Docker container network configuration allows access to 192.168.11.0/24
4. Test direct connectivity: ping 192.168.11.211 from NPMplus container

🔒 SSL Certificate Status

Verification Steps

1. Check Certificate Status:

   ssh root@192.168.11.11 "pct exec 10233 -- docker logs npmplus | grep -i 'cross-all\|letsencrypt\|certificate' | tail -20"
   

2. Check Nginx Config:

   ssh root@192.168.11.11 "pct exec 10233 -- docker exec npmplus nginx -T | grep -A 15 'cross-all.defi-oracle.io' | grep -E 'ssl_certificate|listen.*443'"
   

3. Test HTTPS Access:

   curl -I https://cross-all.defi-oracle.io/

📋 Next Steps

1. Verify DNS Configuration

Ensure DNS A record exists:

Type: A
Name: cross-all
Domain: defi-oracle.io
Value: [NPMplus Server Public IP]
TTL: 300

Verify DNS:

dig cross-all.defi-oracle.io +short
nslookup cross-all.defi-oracle.io

2. Wait for SSL Certificate

• Certificate issuance typically takes 1-2 minutes
• Check NPMplus dashboard for certificate status
• Verify certificate appears in nginx configuration

3. Test Production Access

HTTP (should redirect to HTTPS if Force SSL enabled):

curl -I http://cross-all.defi-oracle.io/

HTTPS:

curl -I https://cross-all.defi-oracle.io/

Admin Panel:

curl -I https://cross-all.defi-oracle.io/admin

Browser Test:

• Navigate to: https://cross-all.defi-oracle.io/
• Verify SSL certificate (green lock icon)
• Test wallet connection
• Test admin panel

🔧 Troubleshooting

502 Bad Gateway

Possible Causes:

1. Backend server not accessible from NPMplus container
2. Network routing/firewall issues
3. Backend nginx not running

Resolution:

1. Verify backend is running: ssh root@192.168.11.10 "pct exec 2101 -- systemctl status nginx"
2. Test connectivity: ssh root@192.168.11.11 "pct exec 10233 -- docker exec npmplus curl http://192.168.11.211/"
3. Check firewall rules on both VMs
4. Verify Docker network configuration

SSL Certificate Not Issued

Possible Causes:

1. DNS not configured or not propagated
2. Port 80 not accessible from internet (for Let's Encrypt validation)
3. Rate limiting

Resolution:

1. Verify DNS: dig cross-all.defi-oracle.io
2. Check NPMplus logs for Let's Encrypt errors
3. Wait and retry (rate limits apply)
4. Manually request certificate in NPMplus dashboard

Domain Not Accessible

Possible Causes:

1. DNS not configured
2. DNS not propagated
3. NPMplus not accessible from internet

Resolution:

1. Verify DNS configuration
2. Wait for DNS propagation (up to 48 hours)
3. Test direct IP access: http://[NPMplus-IP]:80 (with Host header)
4. Check firewall/NAT rules
