Cannot connect to atlas cluster

MongoDB University M121: The MongoDB Aggregation Framework
#1

Ive tried a few times to connet to the atlas server for this course and no matter what network im on (Corporate or open, at home etc) i seem to get the following message :
err: couldn’t connect to server cluster0-shard-00-02-jxeqq.mongodb.net:27017, connection attempt failed: SSLHandshakeFailed: QueryContextAttributes for connection info failed with-2146893055 :
connect@src/mongo/shell/mongo.js:257:13

Im using the expression below thats listed on the course.

mongo “mongodb://cluster0-shard-00-00-jxeqq.mongodb.net:27017,cluster0-shard-00-01-jxeqq.mongodb.net:27017,cluster0-shard-00-02-jxeqq.mongodb.net:27017/aggregations?replicaSet=Cluster0-shard-0” --authenticationDatabase admin --ssl -u m121 -p aggregations --norc

@ Thomas_75980

What OS and version are you running? And, if you can, would you try the following command from your command line just to validate that you can reach the server?

ping cluster0-shard-00-00-jxeqq.mongodb.net

remove extra " before this key

@DHz
Im currently running windows 10 latest update and the ping command gets replies no problem .
It may also be worth mentionting that im also runnignthe shell version 4.0.2

@Niss333 That didnt work unfortunately

This batch works for me on windows 10:

cd “C:\Program Files\MongoDB\Server\4.0\bin”
mongo.exe mongodb://cluster0-shard-00-00-jxeqq.mongodb.net:27017,cluster0-shard-00-01-jxeqq.mongodb.net:27017,cluster0-shard-00-02-jxeqq.mongodb.net:27017/aggregations?replicaSet=Cluster0-shard-0 --authenticationDatabase admin --ssl -u m121 -p aggregations --norc

@Niss333 hmm weird that doesnt seem to work either, ill try building another machine to see if its a problem with the laptop

#8

found my problem
apparently the atlas cluster can only be access from a v3 shell. i was attempting to connect from the latest version …
