Live demo stuck with message "Loading..."

Hi, I'm unable to run the online demo. Instead, the message "Loading..." would permanently show up. It only happens in my corporate laptop, as well as that of my colleagues, while in my personal computer it works just fine.

Any clue about what is going on (proxy, JS component, etc)?

Many thanks in advance!!

That's indeed odd. What do you see when you inspect the network tab of the browsers' devtools?
