ServiceUnavailable：WebSocket 连接失败后：服务器连接 neo4j

Question

I want to launch Neo4j on my machine with dokcer. I downloaded it and did it:

docker run -p 7474:7474 neo4j

But on http://localhost:7474/browser/ I have:

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 tried with neo4j/neo4j credentials and it gave me the same error.

I thought to edit $NEO4J_HOME/conf/neo4j.conf and uncommenting:

# To have Bolt accept non-local connections, uncomment this line:
dbms.connector.bolt.address=0.0.0.0:7687

as they say in the following method but I was not able to find the file

Answer 1

You also need to expose the bolt port from the docker container. The default bolt port is 7687.

docker run -p 7474:7474 -p 7687:7687 neo4j
