Unable to run sandbox on "Graph Data Modeling Fundamentals"

Hello @k.mikhailov,

Welcome to the Neo4j Community!

Can you try the following:

  1. In a different tab, go to sandbox.neo4j.com.
  2. Terminate the blank sandbox (click the right-most down arrow to see the terminate action.
  3. Create a new project and select the blank sandbox.
  4. Go back to the course page and see if you can access the sandbox.
