I'm running Neo4J locally on my Mac. I get the following error:

_"WebSocket connection failure. Due to security constraints in your web browser, the reason for the failure is not available to this Neo4j Driver. Please use your browsers development console to determine the root cause of the failure. Common reasons include the database being unavailable, using the wrong connection URL or temporary network problems. If you have enabled encryption, ensure your browser is configured to trust the certificate Neo4j is configured to use. WebSocket `readyState` is: 3"_

Apparently it relates to the fact that I'm connecting to [data-importer.neo4j.io](http://data-importer.neo4j.io) using HTTPS. The browsers on my Mac platform do not allow anything but HTTP connections. It there a way to use bolt+s and configure the browser to trust the Neo4J certificate?

Hello [@nsteblay](https://community.neo4j.com/t5/user/viewprofilepage/user-id/10605)  
For the data-importer plugin, can you try using the download version from here?  
[http://data-importer.graphapp.io/](http://data-importer.graphapp.io/)  
It appears you need to use the Non-TLS exposed version.  
Please let me know if that helps!

Thanks,

Yes, that does it. Thanks!
