Get error when trying to to connect to the cluster from mongo shell

Hi,

Could someone help? Thanks!
I tried the following command to connect to cluster but received errors:
====command line=====
./mongo “mongodb://cluster0-shard-00-00-ji0ez.mongodb.net:27017/test?replicaSet=cluster0-shard-0” --ssl --authenticationDatabase admin --username m220student --password m220password
=====errors=========
MongoDB shell version v3.6.9

connecting to: mongodb://cluster0-shard-00-00-ji0ez.mongodb.net:27017/test?replicaSet=cluster0-shard-0

OK, it’s working now when I tried the following command:

./mongo “mongodb://mflix-shard-00-00-iy1xw.mongodb.net:27017/test?replicaSet=mflix-shard-0” --ssl --authenticationDatabase admin --username m220student --password m220password
