Hi,
I am getting this error while connecting to MQ Manager. I have given correct login credentials and MQ details..but it is throwing the same error.
Any suggestions…
I have my code written as below…

MQQueueManager lObjMQManager = null;
             Hashtable lObjMQProps = new Hashtable();
            
            lObjMQProps.Add(MQC.CHANNEL_PROPERTY, "Mychannel");
            lObjMQProps.Add(MQC.HOST_NAME_PROPERTY, "MyComm");
            lObjMQProps.Add(MQC.USER_ID_PROPERTY, "xyz");
            lObjMQProps.Add( MQC.PASSWORD_PROPERTY, "abc" );
            
            try
            {

                lObjMQManager=new MQQueueManager(aStrQueueManagerName,lObjMQProps);
            }
            catch (Exception ex)
            {
                return false;
                throw ex;
            }
