Connection keep dropping continuously from Client to Capela database

Kubernetes cluster which is connecting to Capella.
The networking setup used is VPC Peering and all ports are allowed, i.e., there is no firewall in between the Kubernetes cluster and Capella.

When the client tries to connect to the data/memcahed port (11207) and other ports, the initial connection happens but it gets disconnected instantly. Please see the attached logs for reference.

Can you please help us in providing any logs from Capella server to indicate why the connections are dropping ?

What SDK?
How do you know the connections are dropping?
What is the message/logging that you see?
Unused connections will indeed be disconnected and Debug messages will be logged. That is nothing to ve concerned about.
