Problem of connection

Can I have some I can not connect with my cluster
if i try to connect i see this message:

b.net.:27017/test?gssapiServiceName=mongodb&retryWrites=true&ssl=true

exception: connect failed

Can you paste the exact command you used?
It says authentication failed/connect failed
Most likely you have not changed the pwd in your connect string or not supplied the correct pwd

mongo “mongodb+srv://m220student:@mflix-xxxx.mongodb.net/test”
