Looker Studio is now called Data Studio.

Looker Studio is now called Data Studio. The website and endpoint change from lookerstudio.google.com to datastudio.google.com. You do not need to update your reports for this change, as Data Studio automatically redirects to the new domain. However, if your company uses proxies to restrict access to external sites, your IT administrator needs to add the new domain to your access control list (ACL). The names for associated API, client library, CLI, and Identity and Access Management (IAM) resources remain unchanged. For more information, see Data Studio returns as new home for Data Cloud assets.
