I have control of domain www.kempeleenpyöräpaja.fi, and I'd like to host my static web apps there. I'v made DNS Zone named "xn--kempeleenpyrpaja-6nb63a.fi" in azure, and changed name servers of domain to match DNS Zones name servers. DNS lookup tools now show Azure as my DNS hosting provider, as it should be.

But when I'm trying to add record set for my DNS Zone, Static Web Apps is unable to validate my DNS Zone. Using DNS name gives error "Name xn--kempeleenpyrpaja-6nb63a.fi is not valid.", and after changing to "www.kempeleenpyöräpaja.fi" it first gives green text "validated", but after refresh it changes to "unknown error".

I tried to add record sets from DNS Zone as alias records, and found my swa under Azure resources. I added both a and www record sets, but navigating to my home page still gives 404 error. Feels like I'm missing something important, pls help :D
