I can't connect to my Neo4j Sandbox using CodeSandBox. I am taking the Graph Academy course Building GraphQL APIs using Neo4j GraphQL library. The paraemeters in .env are correct. I attached a screen shot of the sandox connection config and the codesandbox results.

Hello @gregwmarvin ,

Your settings in the .env file look correct. Did you save the .env file? Try closing it and reopening it to make sure the settings are still there.
