Hello, I have a problem with the deployment/display of a dashboard on a machine within a network with very high security rules.

On my personal network, the dashboard (which I created with uibuilder) displays correctly: I have a table that is populated by data from another service. Every 3s, thanks to uibuilder.onchange, the table refreshes.

However, when I open this page within the secure network, the table is empty and doesn't populate.

I can add rules to the firewall, and I think I'm missing some allow (I'm sorry for my lack of network and security knowledge)

What should I add? Obviously, I've authorized HTTPS traffic (443) on the machine in question. Could this be due to Websockets?  
Also, the machine is running ubuntu and i'm using chrome.

Thanks a lot for your help 🙂

Open the browser developer tools in the browser showing the empty dashboard and see if there are errors in the console, or in the network tab.

You do need to allow websocket connections from the browser to the server.

could it be a cache issue?

I've fallen for that trap a few times in my early days.

Most likely it was the websocket issue, but unfortunately @mathisfchx has not responded.

Hi everyone,  
Sorry for the delay,

It seems that it was coming from the very old version of the browser (Edge).

Problem is fixed ! Thanks
