Optotrak connects through script but not Vizconnect

[amir]

I use the below code to connect to Optotrak and it works perfectly.

#opto = viz.add('optotrak.dle')
#body = opto.getBody(0)
#viz.link(body, viz.MainView)

However, I can't get it to work with Vizconnect. It's always a red X in the Status column. I've tried it with my computer's hostname and the default hostname in Vizconnect and nothing has worked.

Is there anything I can do to troubleshoot Vizconnect? I'm not sure how Vizard can connect with Optotrak through the script but now through Vizconnect.
