Hi, I am setting up Unity Catalog in my environment, I have a workspace with 2 clusters, the older one (10.4 runtime and non-isolated shared mode) without Unity Catalog configuration and the new one with Unity Catalog enabled (13.3 runtime and shared mode). .

The problem I'm having is when I try to connect to Kafka (running on my aks cluster). I try a telnet connection from the old cluster and it works, but it doesn't work when I try from the new cluster with the Unity catalog setup.

This is what I got when I ran the telnet command from a notebook:

Trying 10.40.12.243...
Connected to 10.40.12.243.
Escape character is '^]'.
Connection closed by foreign host.
