It shows me error as
Error: couldnt add user: there are no users authenticated

Are you able to get past this?

Try to login with the user

Hi @RK30,

No …Its same error…

It means you are already have a user configured. It means the localhost exception is not available anymore. It means you have to authenticate to do anything. Please go back in earlier lessons and read about the localhost exception.

I tried this link

which works for default port, but same steps not working for port27000.


You get

because authentication is enabled AND you have to authenticated. There is 3 ways to authenticate
1.command line arguments
2.connection string
3.db.auth() shell command
