Neo4j Browser window is not opening

I'm unable to proceed the course when I reached the page of 'Challenge Retrieving Nodes'. It is showing 'Configuring Sandbox, please wait' on the right side panel.

Thanks Elaine, it worked for me!!!!

Hello @AnneMariya ,

In another tab, open sandbox.neo4j.com, then refresh the GraphAcademy page. That should do the trick.
