How do I resolve the error "Connect timeout on endpoint URL" on Amazon SageMaker?

Resolution

To connect to AWS services, the notebook instance's subnet must have a virtual private cloud (VPC) endpoint for the service that you connect to. Or, the subnet must be able to access the internet.

Use one of the following options to resolve Connect timeout on endpoint URL errors.

Add a VPC endpoint for the service to the notebook instance's subnet

Many AWS services offer either an interface endpoint or a gateway endpoint. For more information, see AWS PrivateLink concepts. If the AWS service that you're connecting to doesn't offer an endpoint, then you must create a new notebook instance to add a VPC endpoint.

Create a new notebook instance

With direct internet access

The default option is to create a new notebook instance with direct internet access, regardless of whether you create the notebook instance in a VPC.

SageMaker provides a network interface that allows the notebook to communicate with the internet through a SageMaker managed VPC. For more information, see Understanding Amazon SageMaker notebook instance networking configurations and advanced routing options.

Without direct internet access

Add a NAT gateway to the subnet. The NAT gateway allows traffic to reach the public endpoint for the service that you're connecting to.
