Solution 1:[1]

Check the Mongoose version in the package.json file.

With version v6+ you should not add useNewUrlParser and useUnifiedTopology options, so you should remove these options. Mongoose will set them to true by default.

Solution 2:[2]

Can you try this?

mongoose.connect('mongodb://<user>:<pass>@cnox-beta-document-db.cluster-cvzxy5kwx8pn.us-west-2.docdb.amazonaws.com:27017/cnox?replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false', {
  ssl: true,
  sslValidate: true,
  sslCA: `path_to/rds-combined-ca-bundle.pem`
});

Reference.

PS: You might want to remove the credentials from your initial question.
