How to connect to neo4j databases installed on GCP VM (using private IPs only ) thru browser?

Hi, I am facing challenges to connect to neo4j database.

Neo4j is installed on GCP Virtual machine with only private IPs.
firewall rules are created to allow communication from my local machine to VM for ports 7474 and 7687.

do I need to enable any other ports?
the browser displays the options to enter login details and never allows the connectivity.

which login credentials are they asking, is that neo4j??

Have you correctly set the advertised addresses?

Yes, below is advertised config

server.default_listen_address=0.0.0.0
server.default_advertised_address=10.0.0.63 (internal vm ip)
server.http.advertised_address=:7474
server.bolt.advertised_address=:7687
server.https.enabled=false

yes, neo4j/bolt(protocol) login credentials for database.

Is 10.0.0.63 accessible from the host, or is that the internal VM network?

Firewall is enabled to access 10.0.0.63 from local machine when connected to VPN.
the challenges is only to establish database connection using correct login credentials, the same works with python script.
