ERROR Unable to connect to the Mongodb database

When im trying to run my bot it gave me this error:

ERROR Unable to connect to the Mongodb database. Error:MongooseServerSelectionError: connection <monitor> to 52.201.119.106:27017 closed 

I don’t know why that gives me an error, the last time I ran the bot it worked.

Make sure to allow access from everywhere by whitelisting the IP address 0.0.0.0/0 to use MongoDB Atlas from Glitch.
