Neo4j Desktop, Database failed to start

Question

During the installation, there's a problem with the connection to the database. After, when I'm in Neo4j desktop there's this problem:

Conflicts occurred

Database xxx can not be started due to conflicts with external processes. To fix this problem, let us change these port configurations:

bolt: 7687 → 11005 http: 7474 → 11006

But also changing the port it doesn't run.

EDIT: The specific error is:

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

Answer 1

Open Task Manager, and check if there is a service called Apache Common Daemon?

If yes, you may need to turn it off by going to the bin directory, open PowerShell, and then try this:

Import-Module Neo4j-Management.psd1
Invoke-Neo4j status

If it says Neo4j is running even though you don't run anything, you will want to turn it off by using

Invoke-Neo4j stop

I do not guarantee that this will work. See more: Windows installation - Operations Manual

Answer 2

Its because the last running instance of neo4j database was not shutdown properly. Close Neo4J Desktop On windows, open task manager and look for a process named "Zulu Platform x64 Architecture" and kill it. Now re-attempt opening the db. On Linux - You would need to find out what the process is called (assuming that problem occurs there)

Answer 3

I had the same problem. I noticed that my database did indeed start... I just refreshed neo4j desktop(Reload in the Developer tab or just ctrl+R) and voilà! It's solved Hope it works for you as well
