Hello,  
I'm trying to test for the first time yFiles Neo4j Explorer, but, although i've placed the correct bolt port and password (those being the sole default requirements),

Using or not the encryption has no effect.

But your database is up and running?  
What version of Neo4j are you using?

What happens if you just click on the top-green-box ?

What's that?

Yes, of course, everything was running, i used GraphXR successfully before switching to yFiles for a test. And you can see all details in the pictures i've attached to the post.

Nonetheless, since then, i've upgraded both Neo4j and re-imported the application, and issue has dissapeared.

Using yFiles as we speak - quite nice for it's hierarchical layouts. I've actually used these exact yFiles layouts in Cytoscape before this became a Neo4j app.
