Something happened when I used Milo,I do not know why it happened:

UaException: status=Bad_SessionClosed, message=The session was closed by the client. at org.eclipse.milo.opcua.sdk.client.session.SessionFsmFactory.lambda$null$1(SessionFsmFactory.java:159) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)

It looks like you’re trying to get the Session but nothing has called SessionFsm::openSession. You’ll have to share some code, because this is normally done by the SDK if you are using OpcUaClient.

Did you call OpcUaClient::connect before using it?
