WebSocket/Docker issue | Settings for Neo4j Docker Compose with Causal Cluster?

[tsjota]

Hi, I just need a pointer on what settings avoid this error, so I can use Neo4j browser in a cluster.

"ServiceUnavailable: 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"

I finally got this Docker Neo4j cluster up and running.

After lots of trial and error , this is what I found to work:

(1) docker-compose.yml

version: '3'

networks:
lan:

services:

Then finally:

1. browser:
   0.0.0.0:1474

2. log in through:
   neo4j://0.0.0.0:1687
