Hi, I have installed neo4j, it was working fine.

But few hours back, I have done re-installation, from that moment, it is not working, I am not able to login and getting the below error.

I am using Community Edition, Neo4j version is Neo4j 4.1.3

Neo.ClientError.Security.AuthenticationRateLimit: The client has provided incorrect authentication details too many times in a row.

tried :server change-password and the response as
Password change
Please connect to a database to change the password
what should I do now?
tried service neo4j status in terminal and the output is

if you did a re-installation, it seems likely that your old system database is still hanging around. It might be in a location like /var/lib/neo4j/data/database or someplace close to that.

When you first set an initial password, it gets written to the system database. You can't set an initial password twice; so if you have an old system database hanging around, that's probably blocking you from creating a "new initial password".

The solution would be to delete your old database folders and start fresh, understanding of course you're destroying all the old data by doing that.

Yes, I removed everything completely, and done the fresh installation already, now it works

Thanks for your reply :smiley:

I was getting this error on fresh AMI build after one incorrect entry. Had to SSH into instance and run

sudo service neo4j stop
cd /etc/neo4j
./reset-password-aws.sh
sudo service neo4j start

This will set pw to the instanceId, something like i-0e9ff11b7xxxxxxxx
