Can't connect to Atlas cluster using command given in the lab instruction of Chapter 1

Hi, I have been trying hard but still unable to figure out why I am unable to connect my Atlas cluster to IDE .

I tried connecting to my shared cluster named “Sandbox” by choosing to connect with ‘I have mongo shell installed option’ as instructed into the lab manual and copied -pasted the below command as per my cluster config , into the terminal IDE

mongo “mongodb+srv://” --username m001-student

After trying multiple times still my connection has not been established yet.
Error : Location 8000 : authentication failed

Please help me to know more about this error and how to fix it for a successful cluster connection.

It usually means wrong user name or password.
