Hi Kyle,
Have you created an account with Stardog Cloud (https://cloud.stardog.com)? We recommend accessing all our applications, Studio, Explorer, and Designer (Stardog Applications | Stardog Documentation Latest), through Stardog Cloud.
Once you create an account with Stardog Cloud, you can add your local host connection by clicking New Connection and entering the details to your server.
After adding the connection, you'll be redirected to your connection's page in Stardog Cloud, where each of our applications can be accessed.
Thanks for bearing with us as we transition to Stardog Cloud! I'm sorry that it has caused you confusion. In the new year, we will redirect all access to Studio through https://stardog.studio to be through Cloud. Here's the community announcement with more details: Studio and Explorer will transition to be accessed exclusively from Stardog Cloud!
I hope this helps!
Laura
