I am trying to preview my UI Builder page via the preview button. It was working up until a few minutes ago and now I get this error from my browser:

What browser/OS are you using?

Chrome/Windows & firefox/windows.

I figured out what’s going on. When I am on my client’s VPN. I get that error. When I disconnect from the VPN then I can access the site no problem.
