Cluster Connection failed

Hi , I have followed all the steps correctly but i cannot seem to connect the Atlas cluster with shell and i am stuck. Attaching the screenshot of the error. Also cluster name is sandbox and username is correct too.

bad authentication means wrong combination of userid/pwd
Did you pass password as parameter or typed/pasted in response to a prompt?

Sometimes spaces/invalid characters cause issues
Double check your id/pwd

I am getting the same issue. I typed in the password.

What is your URI?

Authentication error means wrong user name or password. Double check.

I can connect to your cluster
You may be typing wrong pwd
Pass the the password as a parameter with your connect string
That way you can avoid typos/space/invalid characters
