I got this error 3 times in a row, and then without changing anything, it started just fine on the fourth try (while I was still searching for a real solution). It's just the standard buggy behavior and poor support we have come to expect from Neo4j. – Fascination

Ran into something very similar, going to cross-link because this was the first hit I got when I was searching for answers, mine was a java process that got left running It got downvoted already which I was a little confused about. Anyway, hope it helps another lost soul. – Kerguelen

Answer 1

It might be your neo4j was still running. I solved this problem by shutting down the database and restarting it.

Platform: Windows 10; Neo4j Desktop version: 1.1.13

Open a commend-line window and go to the directory of your neo4j database. run

bin\neo4j status 

to check the status of your database.

If it is running, run

bin\neo4j stop

to shut down your database. Then go back to the Neo4j Desktop, click the start button, and it could be symptom-free.

Answer 2

I had the same problem and the issue was resolved when I cloned the graph I was connecting. Thereafter, I could connect to the new graph without any problem.

Unfortunately, the only thing helped me is the program reinstall – Ultramicrochemistry
