Hi, services.viya.sas is the dns name used for the internal routing only. To find the base url for accessing the environment through a web browser, check the Outputs tab of your deployment in the AWS CloudFormation UI. The url would also be in the email you received if you specified the OperatorEmail parameter in your Quickstart deployment.
All the services are up and running and I can access all the components of SAS Viya
The SAS Users Group for Administrators (SUGA) is open to all SAS administrators and architects who install, update, manage or maintain a SAS deployment.
