Login fails with "Please provide an email address with a valid enterprise domain"

Issue

When registering a new account in the Real-Time DX Console, the following error occurs

Please provide an email address with a valid enterprise domain.

This affects only new registrations. If you already use a disposable email, you will still be able to log in.

Solution

In order to register for a new account on Real-Time DX, it is required to utilize an enterprise email address. The use of temporary (disposable) or free email addresses is not permitted for the purpose of registering a new account on Real-Time DX.
