Unexpected error code 13 while fetching data Sprin

问题:

It was working fine suddenly this issue popup since 18th Dec, could not find any clue, what suddenly this exception is coming continuously after 6 month working fine.

I am not able to reproduce in local standalone and but it comes in The docker images with micro-services and one of these communicate with Azure even hub.

I have search and found this post. In this post also reported same issue what i am facing but could not find any resolution or clue so I am posting this question.

Please refer below stacktrace:

There was a recent change where an instance of UnknownServerException was changed to a NetworkException - this unintentionally changed consumer client retry behavior. File an issue here - https://github.com/Azure/azure-event-hubs-for-kafka/issues - with your namespace info. Thanks!
