[QUESTION] Unable to connect to Neo4j Desktop graph instance

[es50678]

• Neo4j version: 4.0.1 Enterprise (via Neo4j Desktop 1.2.7)
• Neo4j Mode: Single Instance(?)
• Driver Version: 4.0.2
• Operating System: Windows 10 Pro 10.0.19041 N/A Build 19041

index.js

const neo4j = require('neo4j-driver');

const driver = neo4j.driver('neo4j://localhost', neo4j.auth.basic('neo4j', 'root'));

driver.session().run('CREATE (:Category {name: "verification" })')
  .then((results) => {
    console.log(results);
  }).catch((errors) => {
  console.log(errors);
});

I'm starting my Neo4j instance from Neo4j Desktop. The following is the log output when the instance starts:

2020-04-27 22:03:59.409+0000 INFO  ======== Neo4j 4.0.1 ========

Expected behavior

Running node index.js should result in:

{
  records: [],
  summary: ResultSummary {
    query: {
      text: 'CREATE (:Category {name: "verification" })',
      parameters: {}
    },

    counters: QueryStatistics { _stats: [Object], _systemUpdates: 0 },
    updateStatistics: QueryStatistics { _stats: [Object], _systemUpdates: 0 },
    plan: false,
    profile: false,
    notifications: [],
    server: ServerInfo { address: '0.0.0.0:7687', version: 'Neo4j/4.0.1' },
    resultConsumedAfter: Integer { low: 0, high: 0 },
    resultAvailableAfter: Integer { low: 174, high: 0 },
    database: { name: 'neo4j' }
  }
}

Actual behavior

Running node index.js should results in:

Neo4jError: Could not perform discovery. No routing servers available. Known routing table: RoutingTable[database=default database, expirationTime=0, currentTime=1588025071685, routers=[], readers=[], writers=[]]

Workaround

• Neo4j Version: 4.0.1
• Docker Image: neo4j:4.0.4
• Driver Version: 4.0.2
• Operating System: Windows 10

Currently, I'm getting around this by running neo4j in a docker container.

I use the following to start up the docker container:

docker run -p 7474:7474 -p 7687:7687 --env NEO4J_AUTH=neo4j/root neo4j:4.0.1

This is the same version and username/password used in the Neo4j Desktop instance.

The only difference I can see is that it's running in docker.

The following is the log from starting up the docker instance:

Changed password for user 'neo4j'.

Has anyone else ran into this? Can you help point me in the right direction?

I intend to continue using the docker instance instead of Neo4j Desktop, I'm just curious as to what the difference is that's causing my issue.

I have the same issue. When using the latest version of the driver I cannot connect to my Aura instance at all. I get the same error.

[zhenlineo]

@es50678 You need to configured the advertised address to be something like 0.0.0.0.
Your log already tells you. In the failed case, log contains
2020-04-27 22:04:09.132+0000 INFO Bolt enabled on localhost:7687.

While when using docker, log says
2020-04-27 22:01:39.771+0000 INFO Bolt enabled on 0.0.0.0:7687.

@MuddyBootsCode Try if you have the same, otherwise, be free to start your own issue.

[MuddyBootsCode]

@zhenlineo Will do. It's worth noting that this does not occur with version 1.7 of the driver. It's only when I upgraded that I began experiencing issues.

2020-04-27 22:01:39.771+0000 INFO Bolt enabled on 0.0.0.0:7687.

I changed the following variables in the config file:
dbms.default_advertised_address=0.0.0.0

I tried again and received the same error.

I tried with both const driver = neo4j.driver('neo4j://localhost', neo4j.auth.basic('neo4j', 'root')); and const driver = neo4j.driver('neo4j://0.0.0.0', neo4j.auth.basic('neo4j', 'root'));

Both result in the same error message:

Neo4jError: Could not perform discovery. No routing servers available. Known routing table: RoutingTable[database=default database, expirationTime=0, currentTime=1589408119298, routers=[], readers=[], writers=[]]

}

In addition, I also tried changing the following config variables in addition to the default advertised address:

dbms.connector.bolt.listen_address=:7687
dbms.connector.http.listen_address=:7474

@MuddyBootsCode did it work for you after changing the advertised address? Am I changing the wrong config variable?

[oskarhane]

The dbms.default_advertised_address should never be 0.0.0.0, it should be something that's reachable.
I think the driver using neo4j:// scheme can't handle that when building it's routing table.
If you try bolt:// instead of neo4j:// I suspect it works.
But the real fix is to advertise something else, that's reachable.

The dbms.default_listen_address could be 0.0.0.0, if you want the dbms to accept connections from anywhere.

[mikefontaine]

I'm having the same issue using Neo4j desktop and bolt:://localhost:7687. This is happening with both JS and C#.NET. Everything worked fine until I upgraded to 1.1.21. I uninstalled and tried again on 1.2.8 and I have the same issue. I have confirmed that 7687 is not blocked and that the DB is running. I was able to connect using the REST interface in JS. I even disabled TLS in case that was a problem.

Was there a change in 1.1.21 that might account for this? It seems that the BOLT protocol just isn't working.

dbms.connector.bolt.enabled=true dbms.connector.bolt.tls_level=DISABLED

# Bolt SSL configuration #dbms.ssl.policy.bolt.enabled=true #dbms.ssl.policy.bolt.base_directory=certificates/bolt #dbms.ssl.policy.bolt.private_key=private.key #dbms.ssl.policy.bolt.public_certificate=public.crt

[es50678]

@oskarhane

I changed:

• dbms.default_advertised_address to dbms.default_advertised_address=localhost
• dbms.default_listen_address to dbms.default_listen_address=localhost

I tried with the driver using neo4j://localhost and bolt://localhost.

Unfortunately, neither worked, I'm still receiving:

Neo4jError: Could not perform discovery. No routing servers available. Known routing table: RoutingTable[database=default database, expirationTime=0, currentTime=1589408119298, routers=[], readers=[], writers=[]]

I'm sorry that it took me so long to reply. Thank you all again for helping me out with this ❤️
