Thank you for sharing. However, I have already followed the steps mentioned in the article, and I’m still unable to establish a connection.

When using AWS access keys, the connection is successful, which confirms that there are no issues with access to Kinesis or the network configuration.
Additionally, the connection works with DLT pipelines that are not UC-enabled, so it seems unlikely that there are any errors in the IAM roles or policies configured for the instance profile.
