I'm trying to study Neo4J Graphacademy Courses, as my company will start using it soon. But the exercise from cypher fundamentals course is not loading the neo browser window to the right and is returning **[neo4j-sync.auth0.com](http://neo4j-sync.auth0.com)** refused to connect.

Hey @sachinwork33, we get intermittent problems with the sandbox integration from time to time. We completed some major work to fix these problems and increase capacity over the last couple of days so I hope you won't experience these problems again in future.

If you do, feel free to email [graphacademy@neo4j.com](mailto:graphacademy@neo4j.com).
