Wix pro gallery 200 redirect issue

Hi,

Currently, we have set up a 200 code redirect from externaldomain .com/de/eventsgermany to our Wix page, wixdomain.com

The only thing that is not showing is the Wix pro gallery and in the console log, I noticed it’s trying to get the CSS file with the current URL name (window.location.host) when it is actually supposed to get it from the wixdomain.com domain. Currently, it’s getting it from externaldomain.com where it, of course, doesn’t exist.

Is this something that is able to be fixed or does the Wix guys have to fix this?

Thanks in advance.
