Answer 1

The problem for me, was the firewall rule as I am running Kafka on Google Cloud.

It was working for me yesterday and I was scratching my head today for 1 hour thinking about why it doesn't work anymore .

As the public IP address of my local system changes every time I connect to a different LAN or WiFi, I had to allow my local system's public IP in the firewall rules. I would suggest using a connection with a fixed public IP or to check for this whenever you switch/change your connection.

These small changes in the configurations take too much to debug and fix them. Felt like wasted an hour for this.
