In that online training course, we're being asked to use codesandbox.io and neo4jsandbox.com . The exercise is about searching for businessses by name and category In CodeSandbox Browser, click Business Search and then click the pane for selecting a category.

Hey @AdrienLemaire - what are you using for the REACT_APP_NEO4J_URI value in your .env file? Are you using the "Websocket Bolt URL"?

@elaine_rosenber thanks for your reply. It looks like you wrote the same steps already described in https://neo4j.com/graphacademy/online-training/applied-graph-algorithms/part-1/#_exercise I had completed them yesterday before posting this issue. Could that mean that you cannot reproduce the iss…

codesandbox.io is trying to do websocket requests to a neo4j.com sandbox (here at 34.239.207.167:32864), and fails to establish a secure connection because the neo4j.com sandbox has a fake certificate only valid for localhost.

The online course was modified yesterday to reflect these new steps. We will look into the certificate issue with the yelp sandbox. Elaine

Sorry for the disturb, and thanks for the great support!
