Typically, the exception java.nio.channels.ClosedChannelException typically means that a network channel that was previously open has been closed, and a network request is being made on this closed channel. There are a couple of reasons this occurs including network issues but you can try the following:

Check your network connection and ensure it is stable-no issues.

Implement a Retry Policy: Implement a retry policy in your code, so that if a request fails due to a ClosedChannelException, the request will be retried after a certain amount of time.

Try and update the Java Version: If you are using an older version of Java, try updating to a newer version. Some issues arise from bugs in older versions.
