Please make sure that your atlas ip whitelist configured.

If you still encounter CERTIFICATE_VERIFY_FAILED error; it means that you have to use a certificate file while connecting.

Mondroid uses mongo-dart as driver. It seems like certificate based connections are supported in mongo-dart: mongo-dart tls based connection mongo-dart x509 based connection

We may have to add support for selecting certificates to Mondroid in the future releases. Please let me know if you succeed.

EDIT:

• You can use 'tlsAllowInvalidCertificates=true' parameter in your connection string. Example connection string: mongodb+srv://username:password​@hostname/databaseName?tlsAllowInvalidCertificates=true
