Hi,


<div class=""><br class="">


</div>


<div class="">I’m having some issues getting my remote rendering working. It all works perfectly fine with the the default cone from vtk (code from here:


<a href="https://github.com/dmreagan/vtk-remote-render" class="">https://github.com/dmreagan/vtk-remote-render</a> ), but when I adapt the code to use my own model with interpolation, I get the error:</div>


<div class=""><br class="">


</div>


<div class="">"WebSocket connection to '<a href="ws://localhost:1234/ws" class="">ws://localhost:1234/ws</a>' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED”</div>


<div class=""><br class="">


</div>


<div class="">I can see the serve side has rendered, but the client side is blank.</div>


<div class=""><br class="">


</div>


<div class="">My code is below, any help would be much appreciated!</div>


<div class=""><br class="">

<div class="">Many thanks,</div>
