WebSphere Message Broker 8.0.1 and WebSphere MQ 7.5 together - com.ibm.broker.config.proxy.ConfigManagerProxyLoggedMQException: Could not connect to queue manager 'MB8QMGR' (MQ reason code 2495)

I was struggling to import/use any of the sample flows that come with the WebSphere Message Broker 8.0.1 Toolkit, and kept seeing the following exception: -

$ cat /home/wasadmin/IBM/wmbt80/workspace/.metadata/SamplePreparationWizard.log

Digging further, I also found that I was unable to connect to the Broker / Queue Manager from within the Toolkit: -

but the exception was FAR more useful: -

Following the recommendations in the dialogue: -

Having done this, when I re-started Eclipse and attempted to connect to my Broker - this time it worked out of the box.

Additionally, I was able to import and use the sample flow.

Another hurdle vaulted …….
