Connecting an external databaseConnecting an external database

Yandex Cloud holds no responsibility for configuring a remote connection on an external database server side. When connecting an external database which is not a Yandex Cloud resource:

• Make sure the database uses an SSL certificate signed by a SSL certificate authority. You will not be able to create a connection in DataLens if the database uses a self-signed SSL certificate.

• Grant database access to the following DataLens IP ranges (/ is followed by subnet mask length):
