Not able to connect to neo4j which is deployed to GKE cluster

Hi Team,
I have deployed neo4j application via helm (version: 5.18.1) to gke cluster.
and fetched the password from secret (eg: neo4j/xxxxx) after successful installation .
But i am not able to login to the database with all the approach kubectl exec or from cyper-shell from my local and from UI a well (using ip address of load balancer )
It is prompting for me user name and password ( using default user name - neo4j)
Everywhere i am getting same error:
The client is unauthorized due to authentication failure.

Can you please help me on this.

Thanks
Hitesh
