WebSocket connection failure. Due to security constraints in your web browser

Question

Today I download neo4j-community-3.2.0 in windows, when i start the server, i meet one problem in browser, i meet this problem in neo4j-community-3.1.2 and i had solved it

Answer 1

I ran into the same problem trying to use Neo4j Community Edition on an AWS Ubuntu 16.04 instance. The key thing that solved it was to open port 7687 (the bolt port) in the AWS security group settings.

Found this based on https://stackoverflow.com/a/45234105/1529646

Thus, full answer is:

1. Make sure to configure Neo4j correctly, ie. uncomment the line dbms.connectors.default_listen_address=0.0.0.0 AND the line dbms.connector.bolt.listen_address=:7687
2. Open ports 7474 AND 7687 in the AWS security group settings.
