Authentication problem at neo4j

Hello world, hello humanity.

I am a beginner on neo4j.

I had a version neo4J 2.23 and I made a migration to 3.2.14 on a linux 2.6.18-398.el5 x86_64, which is a remote server.

I configured the neo4j.conf file according to the IP of my server, the port and all that follows.

I run: ./neo4j start

it asks user password: I put "neo4j" which is the default password, since it is the first connection as shown in the attachment neo4j_1.

and afterwards I come across this error """ There was a problem *: * "NotFoundError: Can not execute 'removeChild' on 'Node': the node to delete is not a child of this node." * And the application can not recover. """"
so I can not identify myself.

I hope I can find help, I am on this problem for a week I thank you in advance.

So you successfully changed the password.

What happens when you enter that password in the Mod de passe field?

I don't know what you are trying to do in the query pane? You cannot enter anything in the query pane until your Neo4j Browser is successfully connected to the started Neo4j server.
