NetworkError at data streaming data source

Hello,

I have a problem with teh configuration for the data streaming data source.

I started a project in the local cluster in theevent stream processor:

I also done all like the video tutorial here:

Connect to a streaming data source: Design Studio 1.4 - YouTube

My configuration looks like this:

But every time I push connect I get only "Network Error".

I also tried 9786 as port (like it is shown in the event stream processor).

Does anyone have an idea what I do wrong?

Thanks in advance.

Best Regards

Stefan
