Hello everyone,

I am unable to continue the Cypher Fundamentals course, because the sandbox in the "Retrieving Nodes" challenge is not working. I get this error "Error fetching sandbox" with message "Failed to fetch". I tried restarting the tab, closing the browser and logging out and in again - still doesn't work. Any suggestions?

I found a solution - I just registered here: [https://sandbox.neo4j.com](https://sandbox.neo4j.com) and chose to open with NEuler. After that I was able to connect to the sandbox and everything works fine.
