Orchestrator Installation requirements

I was fine using the Tenant I created at https://platform.uipath.com, however now I am routed to the cloud version of orchestrator, and when I click on the service (my old tenant) I get a error 500 and I cannot access my queues, etc. Can anyone direct me?

Update: Following this link and removing IPv6 allowed me to get into the Service on the first click, after logging into the cloud version of orchestrator.

Thank you,
Patricia
