Connection diagnostic

This tool tests your domains from your network, our datacenter, and Cloudflare's global edge — three independent perspectives to pinpoint where the problem is.

Which service do you have?

Your domain(s) Enter every domain you currently have, one per line. Include the prefix you're using (e.g. cf.yourdomain.xyz).

Username Password

Your credentials are sent over TLS, used once for the test, and never stored.

Replacement domains for your account

Your current standard-issued domain is being blocked. Try this replacement — your username and password stay the same, only the server URL changes.

All replacement options have been tested. If none worked, please open a ticket and include this report.
