Can't login to whatsapp windows from iphone

Hello there,

I can't login to Whatsapp desktop(Windows 11) from my whatsapp (iPhone 11). It always appears error and reverts back to first page that have to click get started. But I can link to whatsapp web and android phone.

I'm sure it's not internet connection problem, because I use the same wifi connection for all device.

Have tried everything including deleting current versions and reinstalling. Both on iphone and desktop.

I have tried to link another phone to the same whatsapp desktop and it worked, I have tried another whatsapp desktop from another laptop also the same issue can't connect. so what is the issue?
