Can't add or use Azure Static Web App with custom domain

Question

Hi,

Adding custom domain name for my Static Web App fails.

I have acquired Azure App Service domain with DNS Zone:

domain name: xn--shkprssi-0za6pb.com

On the Static Web App Custom domains I select the domain on Azure DNS:

This operation crashes with this error

When I try to create a TXT ownership validation it also crashes with error

Earlier I have been trying to add another domain xn--prssishk-5za8oi.live

That also failed with exactly identical error

The domain names contains scandinavian special characters ä and ö and that is the reason why the domain name is in punycode format which is a representation of Unicode with the limited ASCII character subset.

My domain plain text would be: sähköpörssi.com

Is it possible to do something about this issue? Only other option is to change to another web dev technology. I would like to use Azure Static Web Apps.

Thanks for reaching here! This is known and unsupported type of domains causing unpredictable behavior.

Work-around solution: To do the configuration with a new domain (without special symbols/letters) and it's recommended to avoid domains with special characters as they often confuse the algorithms not only in your hosting or registrar settings, but also those related to searches on a global scale.

Hosting a site with a new domain, without special characters would help in resolving the issue.
