Websocket disconnections Unexpected Status of SSLEngineResult after an unwrap() operation-code 1006

Advanced Trade API
1

Hello,
I am using Java Tomcat Websocket Client to connect to your Websocket API, but i am seeing disconnections from time to time with the error “Unexpected Status of SSLEngineResult after an unwrap() operation” and code “1006”.
I have implemented reconnection mechanism and it works fine, but i am trying to figure out why these disconnections occur in the first place. I am not seeing any issues with the pods restarting or network issues as the pods are hosted in AWS Kubernetes.
Any ideas why this is happening and how it can be addressed?

Please ignore my message. Looks like 1006 error occurs when websocket is opened, but not subscribed to any channels for some time.
