qTranslateX and Cloudfront

I’m actually have a website in english/japanese and I’m using Cloudfront.
My origin domain is http://pubisher.my-website.com, and my alternate domain is http://my-website.com. I’ve set a language switcher with qTranslateX and I absolutely have no problem in local and staging.

The thing is, in production, when I switch in english, it redirects me to http://pubisher.my-website.com, not http://my-website.com as it supposed to be.

I tried removing every other plugins, set a default template, still the same problem.
I have some trouble to understand why actually.
Do you have any idea where this problem comes from ?

Thank you a lot in advance!
