Hi All,

I'm receiving the following error for OPC Connections:

> UaServiceFaultException: status=Bad\_UserAccessDenied, message=User does not have permission to perform the requested operation.  
> at org.eclipse.milo.opcua.stack.client.UaStackClient.lambda$deliverResponse$5(UaStackClient.java:337)  
> at org.eclipse.milo.opcua.stack.core.util.ExecutionQueue$Task.run(ExecutionQueue.java:119)

> at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)  
> at java.base/java.lang.Thread.run(Unknown Source)

These are the settings I have. Any help would be appreciated!

If you recently allowed anonymous access but have not restarted, you must do that first.

Otherwise it means you have the wrong username/password specified in the connection settings.
