Hi Neo4j community,

I started the Cypher fundamental courses but the sandbox is not working. Are you experiencing the same issue? Can you help me?

The log issue :

#### BoltConnectionError
No connection found, did you connect to Neo4j?

I tried to log out/ log in, change computer, refresh cookies, but nothing works.

Thanks for your help,
Kevin

Hi! I have the same issue. I have created an account to Sandbox and started 2 projects, but when I'm doing the Cypher fundamentals course the same error message pops up for me after I try to run my query. Do you have an idea what could cause this?

Best regards, Louise

Also, I can confirm that I have already tried to log in an out, and that I just created an account so my sandbox will not expire until in 3 days

You could try typing :server connect and then entering the bolt URI, the user name of neo4j, and the password for the Movie sandbox to connect.

I found also troublesome working with Neo4J Desktop, latest version (1.5.9)
Neo4J Desktop is not for production, as mentioned in this tutorial (Installation - Neo4j JavaScript Driver Manual).
For learning purposes I ended downloading Docker, and running the Neo4J Docker container as mentioned in the link shared above. After that, I was able to run Neo4J browser with no problem, to create and query the Movie DB.

If you still have this problem, changing your web browser may resolve the issue. As a Mac user, using Safari instead of Firefox resolved my problem.
