I am learning k3s. Aa part of that: 1. I have created a k3s cluster with just one server node and zero Agent nodes. 2. Deployed my application using HELM scripts with no network polices in the server pod and want to invoke a SSL Socket connection. I ran below command and getting connection refused error.

curl --include \
     --no-buffer \
     --header "Connection: Upgrade" \
     --header "Upgrade: websocket" \
     --header "Host: example.com:80" \
     --header "Origin: http://example.com:80" \
     --header "Sec-WebSocket-Key: SGVsbG8sIHdvcmxkIQ==" \
     --header "Sec-WebSocket-Version: 13" \
     http://example.com:80/

Currently, I do not have any network policy setup for my k3s nodes which ideally should allow all traffic right?

Please let me know what should I do to make the SSL socket open and work.
