traceGL Javascript tracing tool not picking up my site?

I am able to get the traceGL GUI up and running at localhost:2000 (though it is blank).

WebStorm automatically opens my site at: http://localhost:63342/SuitMe/Site2/index.html#/home

Using the traceGL native live fileserver, I have configured traceGL to point to localhost:63342. I have tried getting it to point to 63342/SuitMe/Site2/index.html#/home using the below:

node tracegl -tgt:63342/SuitMe/Site2/index.html#/home C:\Path\To\Site

but this just results in it pointing to localhost:63342.

As a result, I can't get traceGL up and running. What am I doing wrong?

Many thanks.
