API Access Blocked by Cloudflare - IP Whitelist Request

New IssueDec 29, 2025

Hi Depinscan Team,

We are experiencing issues accessing the Depinscan API (https://api.depinscan.io/api/upload-device-metrics) from our production servers.

Issue:

All API requests from our servers are returning HTTP 403 with Cloudflare challenge pages
The same requests work successfully from local environments
We confirmed this is a Cloudflare block by checking response headers (cf-ray, cf-mitigated: challenge)

Request: Could you please whitelist our server IPs or provide guidance on how to resolve this Cloudflare blocking issue? We can provide a full list of our outbound IPs if needed.

This is affecting our production service that publishes device metrics to Depinscan.

Thank you for your assistance.

Best regards,

MVL Cass

  Hi, thanks for getting back to me. I've checked and the issue seems to be resolved for the IP I shared earlier. Could you also whitelist this IP: 43.xxx.xx.92?

  Oh, but when I run this command,
```
curl -X POST "https://api.depinscan.io/api/upload-device-metrics" -H "Content-Type: application/json" -H "authorization: " -d '{ "uid": "", "events": [ { "custom": { "longitude": 90.2, "latitude": 22 }, "publisher": "device-id" } ] }'
```
  I get the following response.
