Error: Could not connect to the endpoint URL while deploying Tutorial Model

Hello Experts,

I am new to AI Core and followed the Tutorial Series to get to know the environment. (Make Predictions for House Prices with SAP AI Core | SAP Tutorials)


Unfortunately I've encountered an error I am unable to resolve. In the last steps of the Tutorial, while trying to deploy the model on a server, the error "Could not connect to the endpoint URL" appears.

I would be very grateful for your assistance.

For further information: I meticulously followed every step of the Tutorial Series, i didn't change the code from the tutorial except the placeholders that were required to be replaced and the generated model is stored in my S3 Bucket. The Connection to the Bucket is stored in the Launchpad as is the connection to the GitHub. For further information feel free to ask!

Tutorial says

endpoint = "s3-eu-central-1.amazonaws.com", # Change this

 

It should be:

endpoint = "s3.eu-central-1.amazonaws.com", # `s3-` changed to `s3.`

@MichOnSAP : Yes, even for me the model gets created and gets stored in this location. But somehow, during server deployment, this endpoint is not reachable. Apologies to ask again, but were you able to generate prediction URL, meaning the server deplyed successfully?
