In a browser, go to https://<name-or-IP-address-of-the-machine-with-Redis-Enterprise-Software-installed>:8443 to access the Cluster Manager UI. If you use a browser on the host machine, you can also access the Cluster Manager UI at https://localhost:8443.
The cluster generates self-signed TLS certificates to secure the connection. Because these self-signed certificates are unknown to the browser, you must accept them before you proceed.
If the server does not show the sign-in screen, try again after a few minutes.
Select Create new cluster.
