Elsevier DB broken? https://b14bf0da.databases.neo4j.io/browser

I'm following this webinar about COVID: "The Protein Regulatory Networks of COVID-19 - A Knowledge Graph Created by Elsevier"

At 17:25, there is a link to a Neo4J DB developed by Elsevier but it seems to be no longer working

https://b14bf0da.databases.neo4j.io/browser

I get the error:

didn’t send any data.
ERR_EMPTY_RESPONSE

Does anybody know what's up with this?
