Here is what I recommend. Not sure what course you are taking.
The Cypher Fundamentals course uses the movies sandbox.
The Importing CSV Data and GraphData Modeling courses use the blank sandbox.
All other courses use the recommendations sandbox.
Got to your account at sandbox.neo4j.com and terminate the appropriate sandbox.
Go back to GraphAcademy. It should recreate the sandbox a put it in a state that is ready for whatever challenge you are working on.
Let us know if that does not do the trick for you.
Thanks for the suggestion of connecting to the Sandbox, that worked after one creates and loads it
In terms of the training, I was just following the Fundamentals course, got up to the reading data module and the query was not working
There were no errors generated, all that happens is you see the 'connecting to Sandbox' message spin for at least 20 seconds, then you get the following query at the top of the screen
Thanks @Maveri for your feedback.
In general, the sandbox creation and connection should be automatic with no extra input from the user. In some cases, there are problems like yours that come up. We are working to see if we can make the use of the sandbox for a course as seamless as possible for students.
'Do you not see the $neo4j prompt in the right window?'
I can see the '$' without the 'neo4j'.
'Did something change in your environment (ad blocker, connect to a VPN?).'
Not. It just stopped while I was doing the challenge.
'Can you access the sandbox with Neo4j Browser in the sandbox.neo4j.com site (Open)?'
Very strange indeed.
You can execute the Cypher code in the Neo4j Browser window in sandbox.neo4j.com, but you must click the Validate/Verify button to check if your changes to the graph are correct.
If you could provide a Developer Console screenshot when you attempt the Challenge, that might better help us to troubleshoot the problem you are facing.
