Error connecting to db M121

when I try using the connection string provided in chapter one of M121
I see the following error:
“An error occurred while loading navigation: there are no users authenticated”

Hi @Heba_41520,

Please re-check your connection string. You need to use the following connection string to connect to the cluster:

mongo “mongodb://,,” --authenticationDatabase admin --ssl -u m121 -p aggregations --norc

Alternatively, you can download the data dump from the link below. Right-click the download link below and choose “Save link as…”:

Then using mongoimport command you can access the aggregations database.

Please let me know, if you have any questions.
