Common errors

A full URL is pasted instead of a domain.

Fix: Use the domain only, or let the tool extract the hostname from a URL.

The domain does not exist or the lookup returns no data.

Fix: Check the spelling and try again with a valid public domain.

Some dates are missing in the result.

Fix: That can happen because public RDAP data may vary by registry and TLD.
