loads but replaced with a blank screen in Firefox/Chrome

When I open the main website,, it loads but instantly (after a fraction of second) gets replaced with a blank screen, leaving only the chatbot assistant and cookie agreement popup.

This happens regardless of the browser (Chrome, Firefox) and the use of secret mode. The browser’s developer tools say that it has a lot of CORS related errors, as the following screenshot:

I’m not sure this is happening to all users or just some of them, but one of my colleagues working remotely is experiencing the same symptom.
Please take a look and let me access the service!

Now it is working as expected!
