Server Error: You've reached a login page for a domain that isn't using G Suite
The most likely reason for this message is that you have mistyped the name of your domain in the URL. (The Google portion of the URL is correct, since the Google server displays this message.) Check the domain name carefully for typographical errors.
If the domain name is correct, it means that the domain is not correctly registered with Google. There are three possible reasons:
- The domain name has not been signed up for G Suite.
In this case, go to http://www.google.com/a to sign up your domain for G Suite.
- The domain name is configured as a domain alias for another domain, and it is the other domain that is registered with Google.
Although your organization may use several domain names, some of those names may be aliases for your true domain name. You need to use a registered domain name to sign in to the Admin console. Check to make sure you are typing the name of a primary or secondary domain and not a domain alias.
- Your account has been deactivated or deleted.
Google deactivates your account if you do not complete the steps required to verify ownership of the domain within 21 days for G Suite or Education. It is also possible for an administrator at your domain to manually delete the account. In either case, you will need to go to http://www.google.com/a to reregister your domain. You will have to wait 24 hours from the time the account was deleted before reregistering. Any data in the deleted account will be lost.
