not working with worpress.com ?

Hello Matthias,

I used Multiple "Domain Mapping on single site" on a self hosted?wordpress?and it was very useful!

I am trying to use?it on?wordpress.com?(I did a migration for security reasons).

I used the same IP for both domains?A records?on my domain registrar

https://admin.gandi.net/domain/f3559faa-a448-11ec-8509-00163eada87b/climatefresk.org/records

https://admin.gandi.net/domain/f3559faa-a448-11ec-8509-00163eada87b/klimapuzzle.de/records

I setup both domains on?wordpress.com

https://wordpress.com/domains/manage/climatefresk.org/edit/climatefresk.org

https://wordpress.com/domains/manage/klimapuzzle.de/edit/climatefresk.org

Then I did this mapping

https://klimapuzzle.de?>?https://climatefresk.org/de-de

as?worpdress.com?uses nginx, I choose $_SERVER["HTTP_HOST"] (recommended for nginx)?

what happens >

https://klimapuzzle.de?is redirected to?https://climatefresk.org?but not mapped to?https://climatefresk.org/de-de

Can you help me out ?
