The primary container for production variant AllTraffic did not pass the ping health check.

I am trying to deploy a Multi Model endpoint, I am following "https://github.com/awslabs/amazon-sagemaker-examples/blob/master/advanced_functionality/multi_model_bring_your_own/multi_model_endpoint_bring_your_own.ipynb" as my reference.

Everything is successful until "Create Endpoint COnfiguration" step,

When I am trying to create endpoint, I am facing the error"The primary container for production variant AllTraffic did not pass the ping health check."

I checked the cloud watch logs, which are below
