Configuration Status

Your Cloudflare tunnel configuration looks correct! All 10 routes are properly configured.

Configured Routes

#	Hostname	Service	Target	Origin Config
1	explorer.d-bis.org	HTTP	http://192.168.11.21:80	-
2	rpc-http-pub.d-bis.org	HTTP	http://192.168.11.21:80	-
3	rpc-http-prv.d-bis.org	HTTP	http://192.168.11.21:80	-
4	dbis-admin.d-bis.org	HTTP	http://192.168.11.21:80	-
5	dbis-api.d-bis.org	HTTP	http://192.168.11.21:80	-
6	dbis-api-2.d-bis.org	HTTP	http://192.168.11.21:80	-
7	mim4u.org	HTTP	http://192.168.11.21:80	-
8	www.mim4u.org	HTTP	http://192.168.11.21:80	-
9	rpc-ws-pub.d-bis.org	HTTP	http://192.168.11.21:80	noTLSVerify, httpHostHeader
10	rpc-ws-prv.d-bis.org	HTTP	http://192.168.11.21:80	noTLSVerify, httpHostHeader

Important Notes

✅ Configuration is Correct

• All routes point to correct target: http://192.168.11.21:80
• WebSocket routes have proper origin configurations
• All hostnames are configured

⚠️ Domain Difference Noted

• Tunnel Config: Uses mim4u.org and www.mim4u.org (root domain)
• DNS Zone: Had mim4u.org.d-bis.org (subdomain)

This is correct if mim4u.org is a separate domain in Cloudflare (which it is).

Missing: Catch-All Rule

I don't see a catch-all rule in your list. It's recommended to add:

• Path: *
• Service: HTTP 404: Not Found
• Must be last in the list

This handles any unmatched requests gracefully.

Next Steps

1. Verify Tunnel Status

Check in Cloudflare Dashboard:

• Go to: Zero Trust → Networks → Tunnels
• Find tunnel: 10ab22da-8ea3-4e2e-a896-27ece2211a05
• Status should be HEALTHY (not DOWN)

2. Test Endpoints

Run the verification script:

./verify-tunnel-config.sh

Or test manually:

curl -I https://explorer.d-bis.org
curl -I https://rpc-http-pub.d-bis.org
curl -I https://dbis-admin.d-bis.org
curl -I https://dbis-api.d-bis.org
curl -I https://mim4u.org

3. If Tunnels Are Still DOWN

The configuration is correct, but the tunnel connector may not be running:

# Check container status
ssh root@192.168.11.12 "pct status 102"

# Check tunnel service
ssh root@192.168.11.12 "pct exec 102 -- systemctl status cloudflared"

# Start if needed
ssh root@192.168.11.12 "pct exec 102 -- systemctl start cloudflared"

4. Add Catch-All Rule (Recommended)

In Cloudflare Dashboard:

1. Go to tunnel configuration
2. Add new route:
   • Path: *
   • Service: HTTP 404: Not Found
3. Move it to the bottom (must be last)
4. Save

Configuration Summary

✅ Routes: 10 configured
✅ Target: All correct (http://192.168.11.21:80)
✅ WebSocket: Proper origin config
⚠️ Catch-all: Missing (recommended to add)
❓ Status: Check if tunnel connector is running

Troubleshooting

If Endpoints Don't Work

1. Tunnel Status: Check if tunnel shows HEALTHY in dashboard
2. Container: Verify VMID 102 is running
3. Service: Check cloudflared service is running
4. Nginx: Verify Nginx is accessible at 192.168.11.21:80
5. DNS: Check DNS records point to tunnel

Common Issues

• Tunnel DOWN: Container/service not running
• 404 Errors: Nginx not configured for hostname
• 502 Errors: Nginx not accessible or down
• Timeout: Network connectivity issues

Verification Checklist

• All 10 routes configured
• All routes point to correct target
• WebSocket routes have origin config
• Catch-all rule added (recommended)
• Tunnel status is HEALTHY
• Container (VMID 102) is running
• cloudflared service is running
• Endpoints are accessible

Summary

Your tunnel configuration is correct! The routes are properly set up. If tunnels are still DOWN, the issue is likely:

• Tunnel connector (cloudflared) not running in VMID 102
• Container not started
• Network connectivity issues

The configuration itself is perfect - you just need to ensure the tunnel connector is running to establish the connection.
