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.

Hey - sorry I’m just now circling back. Did you fix this issue?

I’m not sure what VNC client you mean. Are you referring to the compute node?

Also where are you seeing this message?
