Unable to load MATLAB via VNC

I’m fairly new to ood and I’m trying to install the MATLAB interactive application. I have installed the prereq vnc applications, however, I’m getting an error that states that the websocket connection “failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED”. I’ve disabled the firewall/iptables on the vnc client, but still getting the same error. Just wanted to check and see if anyone has run into a similar issue and could point me in the right direction.

This looks a little different than the errors I have been wrestling with, but probably worth an ask, have you added the compute nodes to the respective whitelists?

ood_portal.yml

Yes, I’m able to access the node using other interactive apps that a former colleague set up, but not with this MATLAB one I just added.
