SignalK connection: instrument panel shows no displays

[kailolo]

First post, having a blast but slower progress as I am not too technical.

I am trying to make simple racing display showing SOG, heading etc.  

I can't see any instruments and I don't think my signalK Instrument panel is connecting.  I click on button to connect (far right upper corner) and then click on: Connect to ws//localhost:80  I have setup an Input: SignalK TCP  localhost 10110 connection in Signal K 

I have installed the Instrument Panel under SignalK from Github.  

Running 2.0.11-beta Openplotter settings, RPi3+, Globalsat ND-105c

Thanks in advance!  Presume I know no networking or coding terms but I can google of course and plod through it

Edit: typing Openplotter-network in a terminal gives me: bash o--n--: command not found
